java.lang.OutOfMemoryError: Java heap space

[zdary]

Hi,

after I had updated to smartGWTEE 2.5 2011-04-16 night build.
I get an exception

My application was working with night build 2011-04-04.

I put the following code to the server side

long heapMaxSize = Runtime.getRuntime().maxMemory();

and tested that I have one gigabyte of heap max size.

Cheers,

This actually looks like something's horribly wrong with your IDE and you should restart it and possibly the whole machine. But if you think it's a real error, the starting point is to point the full server logs for the request.
