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.

Solution 1:

Open the Run Configuration for your application (Run/Run Configurations..., then look for the applications entry in 'Java application').

The arguments tab has a text box Vm arguments, enter -Xss1m (or a bigger parameter for the maximum stack size). The default value is 512 kByte (SUN JDK 1.5 - don't know if it varies between vendors and versions).

Solution 2:

It may be curable by increasing the stack size - but a better solution would be to work out how to avoid recursing so much. A recursive solution can always be converted to an iterative solution - which will make your code scale to larger inputs much more cleanly. Otherwise you'll really be guessing at how much stack to provide, which may not even be obvious from the input.

Are you absolutely sure it's failing due to the size of the input rather than a bug in the code, by the way? Just how deep is this recursion?

EDIT: Okay, having seen the update, I would personally try to rewrite it to avoid using recursion. Generally having a Stack<T> of "things still do to" is a good starting point to remove recursion.

Solution 3:

Add the flag -Xss1024k in the VM Arguments.

You can also increase stack size in mb by using -Xss1m for example .

Solution 4:

i also have the same problem while parsing schema definition files(XSD) using XSOM library,

i was able to increase Stack memory upto 208Mb then it showed heap_out_of_memory_error for which i was able to increase only upto 320mb.

the final configuration was -Xmx320m -Xss208m but then again it ran for some time and failed.

My function prints recursively the entire tree of the schema definition,amazingly the output file crossed 820Mb for a definition file of 4 Mb(Aixm library) which in turn uses 50 Mb of schema definition library(ISO gml).

with that I am convinced I have to avoid Recursion and then start iteration and some other way of representing the output, but I am having little trouble converting all that recursion to iteration.
