5 "GCJ 4.0 bug workarround" causes crash in high concurreny - ID: 2314764

Last Update: Comment added ( nobody )

Details:

When compiled with sun javac and run with HotSpot 1.5.0, when filesystem is
accessed simultaneously by large number of processes (~50) an occasional
JVM crash will occur on SIGSEGV.

When JVM is run with "-Xcheck:jni", the following error message shows:

FATAL ERROR in native method: Using JNIEnv in non-Java thread

Commenting out lines 213-214 in javafs.c (see attached patch) fixes this
problem.
