Out of Memory Error in java assist 1.0

[saha_subrata]

I am trying to modify the some 1000 class files ,my intension is to insert sys out while entering any method.

and replacing the class file using to byteCode.

Ex Code snippet:--

method.insertBefore(stringToBeInjected);

cc.writeFile();

cc.defrost();

byte[] bytes = cc.toBytecode();

FileOutputStream appendedFile = new FileOutputStream(file, false);

appendedFile.write(bytes);

appendedFile.close();

It is doing iteration for all 1000 class files or so files.

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

at java.util.Arrays.copyOf(Unknown Source)

at java.io.ByteArrayOutputStream.toByteArray(Unknown Source)

at com.nds.epg.debug.engine.ClassPool.write(ClassPool.java:431)

at com.nds.epg.debug.engine.CtClass.toBytecode(CtClass.java:774)

Any help would be greatly appreciated.
