Question

I am getting unitcache exception when I run the GWT application in Eclipse.

I do not understand why it is coming…I also delete the cache files and deploy folder from war folder and compiled the application but it did not worked…

I also restarted the eclipse IDE and tried but result is same it stopped to the “loadCompleteLatch.countDown();” line from PersistentUnitCache.java file…

following is the exception what I am getting:
