Romain Manni-Bucau commented on TOMEE-2458:
-------------------------------------------
[~dkwakkel] nop, this does not look the same issue like that. ParentClassLoader
must be openejb classloader and never the TCCL of an app (it must not be able
to load any app class to be concrete but only server libs except when all are
in the same flat classloader). Here the issue is that the scanned loader does
not match your custom loader strategy since we just respect webapp strategies.
Using WEB-INF/jars.txt or openejb classloader customizer would work since the
scanning and runtime will them use the same list of jars.

> Reporter: Gerwin
> Priority: Major
> Attachments: myclassloader.jar, myclassloader.jar.withtccl,
