The problem comes with implicit compilation.

jtreg is clever enough to know what sources come from which
library directory, but it is /not/ clever enough (and is not supposed
to be) to look inside the library source code and see what code it
references _from other libraries_.

If you tell jtreg to build those other classes explicitly, you will end up
with class files "in the right place".  But if end up with some files
being implicitly compiled, then you risk them ending up in the
same place that explicitly compiled files are going.
