Re: classloader issue on realm setup

The problem appears on "start", if I restart TomEE there is no problem


when you click "Run" on a webapp actually NetBeans calls:
-- un deploy
undeploy?path=/SecureApplication
-- deploy (first call, with good classloader)
deploy?config=file%3A%2FC%3A%2FUsers%2FUtente%2FAppData%2FLocal%2FTemp%2Fcontext3376652197219720975.xml&path=/SecureApplication
-- start (second call, with /manager  contextclassloader in TomEE)
start?path=/SecureApplication

this is the "second call", the bad one

Hi,
I was writing a Tomcat patch to enable JAASRealm to load configuration from webapp classssloader. I noticed that sometimes my realm was "started" using a bad ContextClassLoader (the loader of /manager servlet) 
I was (of course!) using my local TomEE snapshot....
On a simple Tomcat this problem does not happen, on TomEE Realm startInternal is called sometimes with a good CL, sometimes with the bad one 


Bad stacktrace on TomEE:
