Can any one tell me how to crash tomcat deliberately with java out of heap exception

Question

I am looking for a code which will deliberately crash my Tomcat Server.

EDIT (moved from comments)
I did this but it still doesnot crash

ArrayList list = new ArrayList(); 
for (int i = 0; i < Integer.MAX_VALUE; i++) 
{ list.add(new Object()); }

I have tried static Lists, HashMaps but I am still not able to cause java.lang.OutOfMemoryError: Java heap space

Thanks

Any exception that you create from within your code (servlet, JSP, whatever) will almost certainly be trapped by Tomcat. App-servers are designed *not* to crash as a result of a poorly-behaved program. — kdgregory, Apr 30 '14 at 16:15
What is the *real* problem that you're trying to solve? Are you seeing *real* crashes in production? If yes, then edit your question with appropriate information. — kdgregory, Apr 30 '14 at 16:16
I am just looking for a piece of code which will crash my server, and it wont be able to handle any more requests after that — user3565748, Apr 30 '14 at 20:52

Better than dealing with the code itself, reduce the maximum heap size.

Look for -Xmx on your tomcat bin directory and replace whatever value it has with -XmxXXXm where XXX is how many MB will the heap be allowed to get.

I do not want to change the size. I am testing the tomcat as it is – user3565748 Apr 30 '14 at 15:43
