```
    Get the set of properties stored with this service.
    
    Throws:
    
    StandardException
  - getJarReader
```
public abstract JarReader getJarReader()
```
    Get the mechanism to rad jar files. The ClassFactory may keep the JarReader reference from the first class load.
  - cleanupOnError
```
public final void cleanupOnError(java.lang.Throwable error)
```
    Handle any errors. Only work here is to pop myself on a session or greater severity error.
