I am having same problem. I just have to use IBM JDK1.3 because websphere uses it and won't work with anything else.
But I'm very surprised because the LD_ASSUME_KERNEL=2.2.5 must desactive the nptl option and that work fine in RH 9.0 but not in Fedora Core.
Moreover this option is part of the Fedroa release notes.
I don't understand :'(
In RH9 that LD_ASSUME_KERNEL worked just fine. I can't understand why it doesn't work in Fedora anymore. Something
is changed. I hope somebody could explain in more detail why that LD_ASSUME_KERNEL doesn't work anymore.
