Happens on any class that contains a List

rrosen119,
I just got a reply from the dev team and they were unable to reproduce this issue using a class that contains a list. Can you switch to a new workspace and check if you are able to reproduce this issue?

Let me know if the problem persists.

I am getting this same error, on 7.1.1 on both Linux and Windows. Different workspaces and -clean do not help me here...any further info on this apparent bug?

davidwillard,
Can you go to MyEclispe > Installation Summary > Installation details and paste the information here for me. I'll ask the dev team to investigate this issue.

I am having the same problem in 7.5

Hi mikekonikoff,

Can you go to MyEclispe > Installation Summary > Installation details and paste the information here for me. I'll ask the dev team to investigate this issue.

Thanks,
Chakri.
