[eclipselink-users] Map-related Exception in M5

[wintermute@xxxxxxxxxxxxxxxxxx]

Hi list,

I just deployed my application with EclipseLink M5, without any  
trouble this time. For the most part, things look pretty good.
One of my entities, however, doesn't like to have it's map changed.  
The code works in TL Essentials.

Has this been reported? Can I do anything to avoid the issue? (Stack  
trace attached.)

Thanks,

rv
