A DESCRIPTION OF THE PROBLEM :
If jdk 1.4.2 is installed on a clearcase file system then running Java gives
Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.
using strace gives the output
readlink("/proc/self/exe", "/.automount/vob/root/vobstore/linux/java/c/cdft/1/6/ef9c59fcf80d11d881490002b3956847", 4095) = 84
write(2, "Error: could not find libjava.so"..., 33Error: could not find libjava.so
) = 33
write(2, "Error: could not find Java 2 Run"..., 50Error: could not find Java 2 Runtime Environment.
) = 50
_exit(2)

on a normal filesystem this is

readlink("/proc/self/exe", "/usr/java/j2sdk1.4.2_05/jre/bin/java", 4095) = 36
access("/usr/java/j2sdk1.4.2_05/jre/lib/i386/libjava.so", F_OK) = 0
open("/usr/java/j2sdk1.4.2_05/jre/lib/i386/jvm.cfg", O_RDONLY) = 3

It would appear that the clearcase filesystem reads a symlink using readlink that the java application doesn't recognise.
The readlink mechanism is not used in 1.4.0.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Install jdk 1.4.2 on a clearcase system.
run java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java to work as normal and not give any errors.

messages.
ACTUAL -
Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Don't install java on clearcase filesystem.
