1.4.2_02 incompatible with RedHat 9 2.4.20-20.9?

Question

Our program would hang because of a system level lock when running 1.4.2_02 on Redhat 9 2.4.20-20.9 Kernel.
Notice that the MAIN thread is stuck within Sun's code. This is the line of our source code that created the call stack:
System.out.println(this.mFilename + "recordList(" + this.mWorkingDate +") size : " + recordList.size() );
A simple System.out.println can cause such a problem?
Please help. Thanks

Answer 1

You could try setting the environment variable LD_ASSUME_KERNEL to
2.2.5 for linux threads with a floating stack or
2.4.1 for linux threads with out a floating stack.
See the release notes for Linux Red Hat 9. It mentions applications
that do not work correctly with the new threading implementation - java.
It says you 1.4 is ok but I found I need to set this var anyway.
Good luck.
