XmlDocument.setContentAsXmlInputStream() cause EXCEPTION_ACCESS_VIOLATION

Question

Product: Berkeley DBXML 2.3.10
API: java
OS: Windows XP
Hi, I'm new to bdbxml am have a simple test pgm where I'm looping through a directory of xml docs and putting them into a container. Everything works ok using XmlContainer.put(String, XmlInputStream, XmlUpdateContext). Then I wanted to test adding some metadata so I switched to using XmlContainer.put(XmlDocument, XmlUpdateContext). After successfully inserting 3 documents on the 4th iteration the VM crashes executing XmlDocument.setContentAsXmlInputStream(XmlInputStream);
Below is my test code along with the error / dump. The sample doesn't add any meta data, stripped that all out thinking it might have something to do with the error but no luck.

ex.printStackTrace();
} finally {
if (xmlUpdtCtx != null) xmlUpdtCtx.delete();
if (xmlCntr != null) xmlCntr.delete();

And the Error is:

Hi George,
Thanks for the solution. I'm running into an issue trying to build.
Some background information
1. Downloaded Berkeley DB XML 2.3.10.tar.gz from Oracle
2. Environment cygwin on windows
3. Using gcc and g++ (from cygwin distro)
4. Using make (from cygwin distro)
5. Command sh buildall.sh --enable-java
Ran across the following compile error:
In file included from nodeStore/NsDocument.hpp:14,
from Indexer.cpp:24:
nodeStore/NsFormat.hpp: In static member function `static int DbXml::NsFormat::unmarshalMAPMToTemporary(const xmlbyte_t*, M
APMstruct&, Numeric::State*)':
nodeStore/NsFormat.hpp:448: error: call of overloaded `unmarshalInt(const xmlbyte_t*&, int*)' is ambiguous
