Solved: INTERNAL_ERROR when creating container with Java on Vista

Question

I don't know what the root cause is, but I've got a solid test case.
If I maintain a reference to the Environment used to create my XmlManager, then openContainer will barf up a mysterious INTERNAL_ERROR. Setting my reference to the Environment to null eliminates the problem.
I'm using 2.3.10 on Vista with java 1.6. Netbeans 6.0 beta 1
the error:
com.sleepycat.dbxml.XmlException: Uncaught exception from C++ API, errcode = INTERNAL_ERROR
at com.sleepycat.dbxml.dbxml_javaJNI.XmlManager_openContainer__SWIG_2(Native Method)
at com.sleepycat.dbxml.XmlManager.openContainer(XmlManager.java:525)
at com.sleepycat.dbxml.XmlManager.openContainer(XmlManager.java:190)
at restlet.Main.main(Main.java:105)

Oops, haha. I guess rebooting made this go away (!?); I can't repro today.
Here's the test case anyway.

xmlManager = new XmlManager(myEnv, xmlManagerConfig);

myContainer.close();
xmlManager.close();
