On Red Hat 7.1 RC2 java applications will not run. The JDK installed is IBM Java 1.1.8 installed from IBMJava118-SDK-1.1.8-5.0.i386.rpm. Whenever starting java, whether to compile using javac, or run using java, or to start up a jre the process appears to hang. Looking at the process with "ps" we can see that its consuming around 98% cpu. I also tried two other versions of the JDK: IBM Java 1.3 and the linux port from Sun for Java 1.3. The IBM Java 1.3 behaved the same as the 1.1.8 version, while the Sun version allowed me to compile but attempting to run again resulted in a process that was hung consuming 98% of the cpu. The only way to kill the process is to issue a SIGKILL, SIGTERM has no effect. The java application I was attempting to run was a simple "Hello World" application.

The JDK is buggy. You can install the rawhide glibc, and run the JDK with the enivornment variable LD_ASSUME_KERNEL=2.2.5 set, and it should work.
