Out of memory error when calling a MATLAB JA Builder compiled component

I'm having a strange problem with calling a MATLAB JA Builder compiled code in Java. Details are as follows:

1. The code does a load() on a large .mat file
2. If the mat file was opened in MATLAB (by importing the .mat), everything works fine and takes up ~900MB of memory
3. If the code is called from an Java app (which simply imports the function built by JA Builder), I get out of memory from the MATLAB script
4. I have tried setting Xmx really high, but that doesn't seem to do anything at all
5. What is weirder, is that if the java program is run through the Eclipse debugger, it can use up to 900MB of ram and the load() function succeeds

Does anyone know what could be happening?

Thanks in advanced

I have attached a part of the stack trace:

Hi,

Are you properly disposing the native references in your java code?

MWArray.disposeArray(...)

We found not doing that to be a problem for us under certain conditions.

Hi,

I am disposing the references somewhere later down the line, but the load() call is the very first line of MATLAB code to be run and that fails with out of memory.

Thanks
