Java stack overflow error - how to increase the stack size in Eclipse?

I am running a program that I've written in Java in Eclipse. The program has a very deep level of recursion for very large inputs. For smaller inputs the program runs fine however when large inputs are given, I get the following error:

Exception in thread "main" java.lang.StackOverflowError

Can this be solved by increasing the Java stack size and if so, how do I do this in Eclipse?

Update:

@Jon Skeet

The code is traversing a parse tree recursively in order to build up a datastructure. So, for example the code will do some work using a node in the parse tree and call itself on the node's two children, combining their results to give the overall result for the tree.

The total depth of the recursion depends on the size of the parse tree but the code seems to fail (without a larger stack) when the number of recursive calls gets into the 1000s.

Also I'm pretty sure the code isn't failing because of a bug as it works for small inputs.

You need to have a launch configuration inside Eclipse in order to adjust the JVM parameters.

After running your program with either F11 or Ctrl-F11, open the launch configurations in Run -> Run Configurations... and open your program under "Java Applications". Select the Arguments pane, where you will find "VM arguments".

This is where -Xss1024k goes.

If you want the launch configuration to be a file in your workspace (so you can right click and run it), select the Common pane, and check the Save as -> Shared File checkbox and browse to the location you want the launch file. I usually have them in a separate folder, as we check them into CVS.
