Set Solr's data directories directly into the real path, don't use a 
path with a symlink.

Since Solr 9.1, Solr uses a Java security manager that limits what 
rights it has outside of its own directories.

We found problems with this for installs using the service installer, 
because the install dir (usually /opt/solr) is a symlink to solr-X.Y.Z. 
In 9.2.0, that problem is mostly fixed.

Unfortunately, there is still a problem with the security manager if 
symlinks are involved for other directories, like data and logs.  So for 
right now you can't use symlinks for those directories with an 
out-of-the-box setup.

Fixing the remaining problem is going to require some intricate surgery 
on the bin/solr script.  I've begun work on it, but it might take me a 
little while.

Just saw that you edited the security policy directly, which is another 
way to fix it.

Thanks,
