Review Comment:
I see. So Java does not understand symlinks.. Could we instead of setting
this SOLR_SERVER_DIR, open up `/opt/solr-${SOLR_VERSION}/` in the security
manager, so both the canonical and the symlink paths are explicitly allowed? It
feels safer. I.e. something like this
```java
permission java.io.FilePermission "/opt/solr-*",
"read,write,delete,readlink";
permission java.io.FilePermission "/opt/solr-*${/}-",
"read,write,delete,readlink";
```
