Benson Margulies, why is it that you set the TCCL in MockService to begin with? If I remove this, your test passes.

But it also works with the TCCL when adding "com.sun.el" as import package to the "mockwhiteboard" bundle (whose bundle loader you pass in, I suppose by accident, and you meant to pass in the loader of "mockservice" which already has that import?).

So AFAICS don't tinker with the TCCL and all is good We should adapt OsgiIntegrationTest though so it uses @DecimalMin and the test covers the EL usage that way, too.
