The reason for the issue is that some applications may not work correctly after the upgrade to Java version 6u33 or 7u5. This may be caused by an error in the Java Cache and so clearing the cache may resolve the problem.
Please follow the steps below for clearing the Java cache:
1. Close Java application or applet
2. Open Java Control Panel
3. Click Settings under Temporary Internet Files
4. Click Delete Files
Note: This deletes all the Downloaded Applications and Applets from the cache.
5. Click OK on Delete Temporary Files window
6. Restart your application or applet
