i am facing this problem when i open particular type of swings view.
Also tell me where can i find the cache from java
i am using VM parameters like -Xms500m -Xmx700m for ram usage by the application. The moment i try to open this view the ram usage increases to 600M+ and the error is popuped, on clicking send or don't send buttons the application gets terminated.
Last month when i faced the same issue on google i found it can be a malware attack so on formating the machine it worked properly for around 1 and half month and i encountered the same issue again.
