Re: [eclipselink-users] NPE when running with option javaagent:eclipseli

[James Sutherland <jamesssss@xxxxxxxxx>]

It seems to be some issue occurred in weaving your class, PlanResultDetail. 
Does this class have inheritance, and was the super class in the same jar?

You can disable the internal weaving option, which should avoid the issue.
("eclipselink.weaving.internal"="false", in your persistence.xml).
