Hi Martin,
here is a simple test case showing the NoClassDefFoundError discussed in
JDO-194.I does a Class.forName for foo.bar when there is a class
foo.Bar. Attached you find a class Bar, please store it in a directory
foo. Class Main executes the Class.forName. I tried jdk 1.4.2_10 and
1.5.0_05. Both result in a NoClassDefFoundError: foo/bar (wrong name:
foo/Bar). You find the stacktraces attached.
Regards Michael
