Looks good in general with some minor comments below.

These 2 tests look for the first non-public system interface.  Instead 
of keeping the nonPublicInterfaces list, it may be good to simplify this 
to use "java.util.zip.ZipConstants" which seems to be a stable one that 
will unlikely be removed.  I would suggest to add a check that the class 
is non-public (Modifier.isPublic) to catch any future change to this class.

OK.

OK.

I believe your change captures what it's intended to test (typed 
enumeration and rawtype enumeration).  Minor comment - it might be 
better to move the new static variables as local variable before calling 
testEmptyEnumeration to be consistent with convention used in this 
test.  There is no need to keep them static anyway.   I would also take 
out the comment about the substitution since this test doesn't seem to 
have any relationship with javax.swing.

Looks good.  Nit: L46 - good to break it into 2 lines.  It's good that 
you have verified with and without the fix.

OK
