Re: [eclipselink-users] StackOverflow in EclipseLink as shipped with Glassfish 3.1b21
The only pilot error that I can think of that could cause this is completely disabling our cache combined with strings of EAGER relationships.

Yeah, I have a few of those. Even so, I shouldn't be able to cause this through pilot error, I wouldn't think.

    Hi Laird,

     I'll be interested in seeing what the issue is.

     From what you've posted, I see a sequence of EAGER relationships.
     That's where I'd start in looking for the issue.

        I have not yet found the root cause, but thought this would be
        useful anyhow.  I'm getting a stack trace from EclipseLink that
        indicates it is caught in an infinite loop.

        Here is a portion of it:

        As I work to find out more, I'll try to post a test case.
