Error during unzip ...

I am using Java API to unzip a file. The size of the file is 9mb and i am getting the below error. If i upload file of 4mb size, there is no issue in unzipping. But my requirement is 75mb. Since i started with 75mb and got error, i tried until the unzip process gets success. It was 4mb. Files greater than that size is getting this error. Is this a known issue or need to tune with other arguments? I am already running the program with 2GB of memory allocated using memory args.

A fatal error has been detected by the Java Runtime Environment:
