>Description:
triing to find reason why jdk1.5 stop working, I have found that readlink for /proc/curproc/file returns "unknown"
$ truss java
...
readlink("/proc/curproc/file","unknown",1024) = 7 (0x7)
Error: could not find libjava.so
write(2,"Error: could not find libjava.so"...,33) = 33 (0x21)
Error: could not find Java 2 Runtime Environment.
write(2,"Error: could not find Java 2 Run"...,50) = 50 (0x32)
exit(0x2)
$
$ ps ax | fgrep java
