> If a jsp perform some operation (some admin function) which results in restart of various bundle then its possible that org.apache.sling.scripting.jsp bundle also gets restarted. Due to which following NPE is seen in logs. This happens because the 'jspFactoryHandler' in JspScriptEngineFactory becomes null by the time service call returns (due to component deactivation)
> A simple fix might be to create a local copy of jspFactoryHandler and use that (Thanks to Felix for suggesting this!!). Would attach a patch also with the fix
> Uncaught SlingException java.lang.NullPointerException
