bcorder8,
Sorry to hear you are running into this issue. I am afraid I cannot replicate the same at my end.
Please answer below queries to help me investigate further –
1. Open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > Installation Details > [Copy to Clipboard] and paste the same here
2. How did you modify the specific project’s compiler settings to JDK 1.5? Please provide detailed steps.
3. Clear your .log file located at [your workspace dir]/.metadata/.log, replicate the issue and attach file here
