Jeti/2 app crashes during startup

[Yoda_Java6]

Jeti/2 (a Jabber app) works fine here with Java 1.41 or 1.42 - even 1.3 claims to be possible.

Trying to start Jeti/2 using java6 with following cmd file:

---

Set LIBPATHSTRICT=T
SET CLASSPATH=H:\java6a\jre\lib\rt.jar

SET PATH=H:\java6a\jre\bin;H:\Programs\Seamonkey2;%PATH%
Set BeginLibPath=H:\java6a\jre\bin;H:\Programs\Seamonkey2;
SET USER_HOME=H:\Java1\Jeti2\download

H:\java6a\jre\bin\java.exe -jar Jeti2.jar

---

result is:

It creates an error log - attached.

A few times, it created an entry in POPUPLOG.OS2 instead:

The problem is really strange. Even the ​installer crashes here immediately. The crash is somewhere in JVM.DLL as well. Unfortunately I can't debug it as it is somewhere in the JIT/interpreter code that uses various "dangerous" techniques like changing the code segment which often kills the debug info.

I will work on this after Beta 2.

[dmik]

The applications from #49 demonstrate similar crashes in JVM.DLL.

[Yoda_Java6]

I tested with new Beta 2 - same crash as before.
After reading about SMP problems, I turned 1 CPU OFF.
Now Jeti/2 actually starts and runs - but all windows
are missing half of what should be there. There was also
no sound at all (should have been several).

I'm attaching output to cmd window - a lot of java fails.

[dmik]

What I see now is that at some point during Java method execution FS changes from the Win32 value to the OS/2 value. This expectedly breaks the exception chain and probably some other thread-related machinery. I have to find out who is doing that.

[dmik]

The crash should be fixed in r246. Turned out that we were calling OS/2 APIs directly, bypassing their Odin wrappers that save/restore the FS register (in particular, in this case it was the Prf* calls in the getOs2FontPath() method).

Now, the Jeti/2 installer works smoothly.

Jeti/2 itself doesn't work though giving java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.JPEGImageDecoder. This class is missing indeed both in the OS/2 build (b13) and in my own Win32 I made from the original sources build but it's present in OpenJDK6 (b20) for Linux. I will investigate.

[dmik]

Created #60 for the JPEGImageDecoder problem. Closing this defect.
