[OPENJPA-1854] A 'find' or 'query' may return multiple instances of Entities which contain Embeddables, where the Embeddables use String identities, if the id value has trailing spaces.

Description

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.
