I upgraded to 6.0 today and going to glibc-2.1.1 broke my jdk1.1.7. jdk1.1.7 depends on a late version of glibc-2.0.7 as does the port of jdk1.2. I depend on java daily. I noticed that your support registration say to come back on 5/10/1999 to register for 6.0 support, well I need help in running glibc-2.0.7 along with glibc-2.1.1.
jdk messes with glibc thread internals. It shouldn't do that. Make it use native threads and the problem should go away.
I switched jdk 1.1.7 over to using native threads and this appeared to solve the problem. Thanks
