> I'm trying to verify xml signature for an xml of size around 900 MB using the code from [https://github.com/coheigea/testcases/tree/master/apache/santuario/santuario-xml-signature/src/test/java/org/apache/coheigea/santuario/xmlsignature]. After running the code I get OutOfMemory exception.
> In the attachments is image from IBM HeapAnalyzer where you can see the leak suspect (red border), file XMLSecurityInputProcessor.java. The problem is in the class InternalBufferProcessor which buffers all xml events.
> For testing purposes I tried with action XMLSecurityConstants.ENCRYPT which skips the buffering part and the code completes with no exception.
> In the attachments is also a sample of my xml structure (if it matters).
