Need help to identify the root cause of the issue. We had this error throwing up when
1. Some users logs in
2. Users work on some assignments.
Its not consistant as some users are able to login, some users were able to work on assignments ... We did tomcat restart on our nodes and it worked. We need help in identifying the root cause. Attaching the screen shot of error thrown and also the logs ( open in notepad ++).
The shared articles explains about the restrictions imposed on the java2 security and i am not sure how the restart of the server resolved your issue. If you face the issue again kindly let us know for our further investigation.
