linux -ws gtk -arch x86 Reproducible: Sometimes Steps to Reproduce: Ever since upgrading to BIRT 2.5 we've been getting class loading issues on the server and with the designer. These problems didn't exist with BIRT 2.3. Same setup except for the new BIRT. This problem happens intermittently. Unfortunately, we cannot reliably reproduce. The only solution when this happens is to restart the VM.
Can you still reproduce it in latest BIRT?
We haven't upgraded to the newest BIRT yet. We should be upgrading within the next few months. I'd expect the new POJO runtime to solve this issue for us.
