Absolutely.

Almost all of the Java ABI used by GCJ is defined as a subset of
the C++ ABI.  The main exception is handling of "interface inheritance"
and "interface method calls".  A Java interface is basically a
C++ virtual abstract base class with no non-static fields, but it is
implemented in a way that doesn't need "virtual bases" or offset
adjustment.

For example fixing support for namespaces would be very helpful
for Java, as Java classes are organized into packages - which are
basically namespaces.
