Memory leak ? ( legstar 1.5.3 HostToXMLTransformer)

[Guillaume Rumeau]

Hi, I use legstar 1.5.3 in Web Method (Software AG) to transform a cobol message to a Xml one.

I use eclipse plugin to genrate classes. After that, i use bind.HostToXMLTransformer 

This work fine, instead that, because code is not thread safe, i have to deal with a resource pool.

I have a pool of HostToXMLTransformer object.

For each message, i make an HostToXmlTransformer.transform(inputBytes, writer, encoding)

with a HostToXmlTransformer gettted from the pool (with an equivalent of a lock)

But, that' why i write here, messages after messages, memory grows. It sounds like a memory leak, but perhaps it is a misuse of the component, of my hand.

In The dump file i saw that there is a _cobolComplexBindingCache object which is a hash map. Values of my messages are cached in it.

My question is : Why ?

I understand caching the structure, but why the values ?

My second point is, Is it possible to disable this cache or clear it after each message ?

Or is my using of legstar is wrong ?

Thanks for your help.
