Reformat line in Class.privateGetPublicFields() to be more debugger-friendly

A DESCRIPTION OF THE REQUEST :
Please reformat the line

 if (res != null) return res;

in java.lang.Class#privateGetPublicFields(Set<Class<?>>) to

 if (res != null)
  return res;


JUSTIFICATION :
When debugging the recursive method privateGetPublicFields it is often necessary to set a breakpoint at the return statement. Currently this cannot be done. The breakpoint is hit unconditionally.

This causes severe debugging headaches.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Have elegant iconic Java code in the JDK.
ACTUAL -
Must see strange unfavorable idioms in the JDK.

CUSTOMER SUBMITTED WORKAROUND :
Define a conditional breakpoint.
