The package used: j2sdk-1_4_2_10-solaris-*.tar.Z After a dirty install on the same build at the default directory (i.e. /usr/j2se) a symbolic link to the same directory with the same name appears there. (/usr/j2se/j2se -> ../j2se) That link remains even after the removal of all packages.
How to reproduce:
1. Copy the bundle to any machine.
2. Unpack it:
   $zcat j2sdk-1_4_2_10-solaris-i586.tar.Z | tar -xf -
3. Switch user to 'root'.
4. Install the product
   #pkgadd -d . SUNWj3*
   The product will be installed in /usr/j2se.
5. Install the product again. Agree to ovewright all conflicted files.
