We are currently having a problem of Java Heap Space and the log shows the problem is when the transofrm method is called.

Resuming our implemetation is something like this:

	Transformer transformer = cachedXSLT.newTransformer();
	String strXMLInput = this.toString();
	StringReader xmlReader = new StringReader(strXMLInput);
	transformer.transform(new StreamSource(xmlReader), result);

Where cachedXSLT is a Template and result a javax.xml.transform.Result

The log shows this:

Analysing the heap its shown that the heap is occupied mostly by ByteArrayOutputStream

My question is: Does transform keep any cache or anything that the garbage colector is not able to grab?
