Description

I get the following exception when I try to merge an entity which contains a java.util.Calendar field.

I'm running the test in eclipse and my classpath probably isn't set up to properly display the openjpa version,
output from svnversion -c : 406193:505052M

It looks like we're missing a case statement for JavaTypes.CALENDAR in org.apache.openjpa.kernelAttachStrategy.attachField. I added one under JavaTypes.DATE and that resolved the issue for me.
