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:
java.lang.Exception: cl=WebappClassLoader
context: /manager
delegate: false
