                 URL: https://issues.apache.org/jira/browse/OPENJPA-1854
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 2.0.0, 1.2.2, 1.3.0
            Reporter: Heath Thomann

This issue is very similar to that of OPENJPA-1501, with one twist.......I've found that when
you have an Embeddable, which has Strings as the keys/ids, openJPA code puts the Embeddable
into an ObjectID by design, rather than a StringID....recall, the fix to OJ1501 was to strip
white space from the end of a user's String key when that String was placed into a StringID.
 So, the strings in an Embeddable would also need to be stripped, just as was done in OJ-1501,
but unfortunately it would seem to be harder to do so for Embeddables since openJPA code doesn't
necessarily know what types are contained in the Embed.
I've created a JUnit test case which has three test methods.  The test is attached here.
