1.4.2_03 (SUNWj3rt) incorrect becomes default java on S10 with 1.5.0 present.

The /usr/java symlink should point to 1.5.x on a S10 system. The
current postinstall script for 1.4.2_03 (SUNWj3rt) grabs control
of the /usr/java symlink even if 1.5.0 is present and already controls
the symlink.

This bug is actually present in all 1.3.x and 1.4.x releases, meaning
they will all disrupt S10 if installed there. So while the first packages
to be fixed should be 1.4.2_04, any future releases of 1.3.1 and 1.4.1 should
also have this fix.
