I'm running Virgo 2.1.0 with Eclipselink 2.0.2 ontop of the default included spring version 3.0.0.
80% of the time I get an Classloader Exception during startup of my application.

As mentioned this happens not on every startup and I don't see any differences if I deploy my plan right during startup or afterwards. Without my custom application everything works fine, the admin application is starting fine.
I checked via telnet and I do not see a difference in bundle states. Neither for kernel nor for user-space bundles. I also did not spot any exceptions before I deploy my custom application. So, for me everything is working fine as it should since I did not modifiy the default configuration.
Does anyone have an idea whats the problem?
