Can you say more precisely what you meant by "immediate Abort"? DId a Java runtime error message appear (e.g. java exception)? If you only saw "Aborted" and nothing else, then it is likely the segv. In that case please try the test using gdb as shown in the bug report; this will stop and display any signal.

Sorry, I forgot to mention that part. I was not able to reproduce the issue an non-updated Karmic. I just get an immediate Abort (not a Segv). -- Segfault in _Jv_SetCurrentJNIEnv in /usr/lib/libgcj.so.10 https://bugs.launchpad.net/bugs/484414 You received this bug notification because you are a direct subscriber of the bug. Status in “gcj-4.4” package in Ubuntu: New Bug description: Interactive Brokers' Trader Workstation is a Java app which was working perfectly in Karmic until a recent update. Now java aborts immediately at start-up with a segfault when running this application. To reproduce this, please download the attached pluginsupport.jar file into an empty directory, cd into that directory, and then run the following command: /usr/bin/gij-4.4 -cp jts.jar:pluginsupport.jar:riskfeed.jar:hsqldb.jar:jcommon-1.0.12.jar:jfreechart-1.0.9.jar:jhall.jar:other.jar:rss.jar jclient.LoginFrame . Notes: In real life I ran /usr/bin/java, which is a symlink to /etc/alternatives/java, which symlinks to /usr/bin/gij-4.4 The attached .jar file appears to be the only file needed to reproduce this segfault; if you want to have the full application, download it from http://individuals.interactivebrokers.com/en/p.php?f=tws (use the 'Unix Standalone' version TWS 899). Regardless of what java code is or is not present, a segfault should never occur. Here is a stack trace obtained by running under gdb: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff6059d32 in _Jv_SetCurrentJNIEnv(_Jv_JNIEnv*) () from /usr/lib/libgcj.so.10 (gdb) bt #0 0x00007ffff6059d32 in _Jv_SetCurrentJNIEnv(_Jv_JNIEnv*) () from /usr/lib/libgcj.so.10 #1 0x00007ffff60178ee in _Jv_GetJNIEnvNewFrameWithLoader(java::lang::ClassLoader*) () from /usr/lib/libgcj.so.10 #2 0x00007ffff60576ba in void java::lang::Runtime::_load(java::lang::String*, bool) () from /usr/lib/libgcj.so.10 #3 0x00007ffff63d3c42 in void java::lang::Runtime::loadLibrary(java::lang::String*) () from /usr/lib/libgcj.so.10 #4 0x00007ffff63bd284 in void java::lang::System::loadLibrary(java::lang::String*) () from /usr/lib/libgcj.so.10 #5 0x00007ffff63e441a in ??
