Signal

Signal SIGUSR1 is not available on Solaris8 for Java VM
Issue:
java.lang.IllegalArgumentException: Signal already used by VM: SIGUSR1
        at sun.misc.Signal.handle(Signal.java:149)
on Solaris8.
It's OK on Solaris10
Solution:
Add a parameter for Java VM on the command line: -XX:+UseAltSigs.
It works well on Solaris8 and Solaris10 after providing such option.
