Jeti/2 crashes on startup

[Yoda_Java6]

Jeti/2 still crashes on startup. Problem started with the GCC builds of Odin.
I have now tested every F***** setting of Jeti/2 to see if any of those can be the difference between our tests.

Well, at the buttom (of course), the setting 'XMPP' seems to be the one causing the problem. When I turn it off, Jeti/2 can start again.

This setting have always been on here - and gives no problems with
Java 1.41, Java 1.42 or Java 1.5 - and also worked with VAC builds of ODIN.

I've checked it. Jeti/2 still fully works here with the latest b25 build. However, your latest log shows that for you it crashes in IPHLPAPI.DLL (GetAdaptersInfo). Which suggests that you have some unusual network adapter configuration. I will check the code.

[dmik]

Checked the code. Visually I don't see any problems. Can you quickly try the debug version? ​ftp://ftp.netlabs.org/pub/odin/test/od.zip. I need the odin*.log files of your failed attempts (and crash logs if any).

Did you enable 'XMPP' as described above ? It only crashes here, when that is enabled.

It crashes both on my laptops and my desktop PC. None of these uses the same drivers.
OpenFire also crashes in IPHLPAPI.DLL - again a completely different NIC setup.

All logs incl pdump available here:

[dmik]

Thanks, investigating.

[dmik]

I can confirm some strange behavior. It doesn't crash here but it gives 100% CPU load if I enable the XMPP plugin. This only happens with the release version of JDK. The debug version works well.

For some reason, the Win32 exception handler is not called in the release build (in the debug build it is). As a result, the unsatisfied exception gets raised again and again.

[Yoda_Java6]

Tried the debug version of Odin with OpenFire too:

​ftp://ftp.warpspeed.dk/pdumps/Crash491.zip

[dmik]

I found the reason why the exception handler did not work -- it's a small but nasty regression of ​http://svn.netlabs.org/odin32/changeset/21999. We didn't pick up the CONTEXT record changes made by the __except filter (if any). I fixed it now and it goes further but then it crashes at some debug assertion. I can't catch it though yet since the debugger is very unstable...

[dmik]

The Odin regression is fixed in r 22004 there.

The debug assertion is fixed in r391.

Now I get a valid crash report from JVM that shows that JVM tries to execute code on the stack (!) and then unsurprisingly crashes due to the access violation exception. This is weird. Looks like some memory gets corrupted.

[dmik]

Btw, can we get the source code of the Jeti/2 and especially of the XMPP plugin? Who has the contact of the author?

[Yoda_Java6]

Jeti can be found at ​http://jeti.sf.net

[dmik]

Just tested it once more with hotspot rebuilt with ODIN_FORCE_WIN32_TIB and it works... really strange.

[dmik]

Yoda, please check the debug hotspot build you may take here ​ftp://ftp.netlabs.org/pub/odin/test/od.zip with Jeti.

[Yoda_Java6]

I downloaded that 7 days ago - and reported back.
It doesn't seem to be updated, so the reports are still the same ???

[dmik]

Mmm, the correct link is ​ftp://ftp.netlabs.org/pub/odin/test/hd.zip. My fault. Please try ASAP.

[Yoda_Java6]

Added that new DLL
Same crash as before in IPHLPAPI

​ftp://ftp.warpspeed.dk/pdumps/LapCrash188.zip

[Yoda_Java6]

Sorry, I installed the DLL in the wrong place before.
After correcting it, I get a different crash:

​ftp://ftp.warpspeed.dk/pdumps/LapCrash192.zip

Maybe this DLL doesn't work correctly with my GA2 version ?

[Yoda_Java6]

Tested same with OpenFire - it looks like same crash as Jeti/2:

​ftp://ftp.warpspeed.dk/pdumps/Crash493.zip

[dmik]

Okay, my last guess that the new crash is because we:

1. Don't maintain the win32 exception chain in non-ODIN_FORCE_WIN32_TIB mode
2. Don't make sure that FS contains the right value around the place where hotspot detects the Thread pointer location (which it detects based on the contents of FS:[0] i.e. the pointer to the exception chain, see source:/trunk/openjdk/hotspot/src/os_cpu/windows_x86/vm/os_windows_x86.cpp​).

1 is easy, 2 requires some thinking. This access logic of the Thread pointer is also used in the code that generates x86 assembly on the fly and I can't find MacroAssembler primitives that could load a desired value to FS so far...

[dmik]

Yoda, one more test please: ​ftp://ftp.netlabs.org/pub/odin/test/od2.zip and ​ftp://ftp.netlabs.org/pub/odin/test/hd2.zip.

[Yoda_Java6]

Testing on my Desktop PC.

Jeti never initializes - something seems to be looping 4ever.
I stopped it with ctrl-C

Crash207.zip attached to this ticket

[Yoda_Java6]

Tested with OpenFire too. It gives the same endless stack dumps in Odin log.

[dmik]

Hmm, looks like you also need the new JAVA.EXE version to properly test it. All the tests above are not valid w/o it. I've added JAVA.EXE as ​ftp://ftp.netlabs.org/pub/odin/test/jd2.zip. Please try again with it and JVM.DLL from hd2.zip.

Please also try another test with JVM.DLL from ​ftp://ftp.netlabs.org/pub/odin/test/hd3.zip and JAVA.EXE from ​ftp://ftp.netlabs.org/pub/odin/test/jd3.zip.

[Yoda_Java6]

Added J2 (hd2 I already had).
Crash is now back to the usual one in IPHLPAPI.
Crash209.zip attached.

[Yoda_Java6]

OK, too big to attach - it is here instead:
​ftp://ftp.warpspeed.dk/pdumps/Crash209.zip

[Yoda_Java6]

jd3 + hd3 added (Notice: hd3 is older than hd2 !).
Same crash in IPHLPAPI - another in POPUPLOG.OS2
​ftp://ftp.warpspeed.dk/pdumps/Crash210.zip

If you need PDUMPS, I can enable them.

[dmik]

Ok, thx, I will analyze them and give you the new versions to test.

It looks like in your case it simply doesn't run to a point where it starts executing the stack here (hd2) since it crashes in IPHLPAPI.DLL. Doesn't explain anything to me so far...

[Yoda_Java6]

Tested j2 on OpenFire.
Crashes seems different - 498 gave guard page errors again - 499 ran a bit further.
​ftp://ftp.warpspeed.dk/pdumps/Crash498.zip
​ftp://ftp.warpspeed.dk/pdumps/Crash499.zip

These include PDUMPS

[Yoda_Java6]

Crash500.zip is OpenFire with j3 and hd3. Guard page warning again.
​ftp://ftp.warpspeed.dk/pdumps/Crash500.zip

[dmik]

Found the bug. Should be fixed in Odin in ​r22006:

iphlpapi: Fix possible crash in GetAdaptersInfo?() and friends.

This could happen under some circumstances due to invalid casting
from int to char. Regression of the switch to GCC (which performs
conversions differently compared to VAC).

The code was wrong and relied on non-standard VAC behavior.

Here's the fixed (debug) version of IPHLPAPI.DLL for you to test: ​ftp://ftp.netlabs.org/pub/odin//test/iphlpapid.zip. Check and report back please. Test JD2/HD2 first.

[dmik]

Note that JD3/HD3 is the build with the old SEH scheme (ODIN_FORCE_WIN32_TIB) and hence the old guard page warnings (and possible crashes) are back -- switching to the new scheme was done in particular to fix these guard page warnings and related problems.

[Yoda_Java6]

Well, it doesn't seem to crash on startup now with JD2/HD2. It used to crash even
if server was unavailable (which it still is).

OpenFire still doesn't work with any of these builds - crashes at startup:
​ftp://ftp.warpspeed.dk/pdumps/Crash503.zip

[dmik]

Do you mean that enabling the xmpp plugin in Jeti also works fine for you?

Regarding OpenFire, the question is in #133.

[Yoda_Java6]

Well, I found an old account on another server to test.
I don't see any crashes in IPIHLPAPI any more - but it seems
to crash in several different ways now.

​ftp://ftp.warpspeed.dk/pdumps/LapCrash204.zip
​ftp://ftp.warpspeed.dk/pdumps/LapCrash205.zip
​ftp://ftp.warpspeed.dk/pdumps/LapCrash206.zip
​ftp://ftp.warpspeed.dk/pdumps/LapCrash207.zip
​ftp://ftp.warpspeed.dk/pdumps/LapCrash208.zip

[dmik]

And how does it behave with JD3/HD3?

And when do the above crashes happen? Enabling XMPP plugin again?

[Yoda_Java6]

It crashes when all is up, just before it is ready to use.
It doesn't matter if XMPP plugin is enabled or disabled.

Now, trying JD3/HD3 crash is gone, and Jeti/2 seems to work !

[dmik]

These problems need to be analyzed further. Moving it to GA4.

[dmik]

We must solve the SEH problem ASAP. Too many apps are crashing with the new scheme (see #171, #173, #174).

[dmik]

Seems that there is one more victim of the new SEH scheme - AOO. Java works in AOO (Apache OpenOffice) if I use GA2 (old SEH scheme) and hangs (with a crash in ODINCDT.DLL) if I use GA3. Here's the POPUPLOG:

ODINCRT.DLL 0002:000000e2

Created #179 for it.

[dmik]

The problem has been fixed in Odin, see ​r22009 there.

A really tiny bug, regression of switching to the new SEH scheme.

Jeti/2 doesn't crash here anymore when I turn on and off the XMPP plugin.

The test version of JDK.DLL is here: ​ftp://ftp.netlabs.org/pub/odin/test/j4.zip. Please test and report.

[Yoda_Java6]

Tested j4 - and it does indeed seem like Jeti/2 is finally stable now :-)

[dmik]

Great. Closing.
