< String string = stringBuffer.toString();

 >         String string = stringBuffer.toString().trim();
I also changed persistence.xml in the unit tests for 2 entries (all but one
type in .xsd is defined as string):

The changed files are attached. If you feel strong about changing all entries in
the test's persistence.xml, let me know.
