> When decrypting a big XML file, i.e. an encrypted XML file with an EncryptedData structure whose <cipherValue> content is around 1.7 Giga bytes, I got systematically a java.lang.OutOfMemoryError: Java heap space.
> The phenomenon observed is that heap used increase rapidly and linearly until out of memory.
> Using JMap & a memory analyzer tool, I found out that there are more than 2 Giga of char[] hold within the XMLSecurityInputProcessor$InternalBufferProcessor.xmlSecEventList  array.
> See attached screen shots.
> It looks like that every processed XMLSecEvent is store in this list (until <END_ELEMENT> tag is encountered ?)
>  See XMLSecurityInputProcessor$InternalBufferProcessor.processNextEvent(...)
> Is it a bug or a design necessity ?
