Installing the sparc native threads version of SUNWjvrt causes /usr/java to
be a symbolic link. A subsequent attempt to install SUNWjvdev gives a
message:
  "WARNING: /usr/java <no longer a symbolic link>
But, SUNWjvrt has just installed /usr/java as a link to /usr/java1.1 .
The installation asks if I want to install these conflicting files (i.e.
/usr/java). I answered "n", and continued with the installation.
At that point, the installation seems to proceed without error.

If this problem is not local to the java/jit workspace, move the
bug to javavm_sol and increase it's priority.
