# rpm -qa java*

java-1.5.0-centos-devel-1.5.0.06-1.i386
java-1.5.0-centos-1.5.0.06-1.i386

% java
Error occurred during initialization of VM

% ls -l /usr/bin/java
lrwxrwxrwx  1 root root 22 Jan 30 16:12 /usr/bin/java -> /etc/alternatives/java
% ls -l /etc/alternatives/java
lrwxrwxrwx  1 root root 38 Jan 30 16:12 /etc/alternatives/java ->

I must be missing something obvious.
