Oh no...

What versions of Sun's JDK won't work with the new NPTL/glibc?

If versions 1.4.1 or greater won't work, has Sun commented on which future
version will work with the NPTL/glibc?

No Java, no RedHat 9 for me. :-(

OK, I found a response from Sun and pasted it below. It seems that 1.4.1
and above will work OK and NPTL specific enhancements are slated to be a
tiger task - I think tiger is Java 1.5 to be releases around December
2003. I hope RedHat mentions Java 1.4.1+ work in the release notes.

BugID: 4802778

JDK 1.4.1 and 1.4.2 run OK on NPTL, the workarounds we have in the JDK
for LinuxThreads are not necessary, but should be benign. NPTL has a
better design and more kernel support. It is expected to replace
LinuxThreads
and become the default pthread library, we should optimize JVM to
better support NPTL, both for reliability and performance. This RFE
is filed to track this effort. It will include isolating LinuxThreads
workarounds, and possibly using new features available in the library
or kernel.
