   I guess you found that already.

   If you build a debug or fastdebug build, they're compiled in.
   J2dRlsTraceLns (Rls -> Release) are always compiled in, even in
   an optimized binaries, so don't use them in performance
   critical places.

   To enable, set J2D_TRACE_LEVEL=N (where is in 1-4), see
   src/share/native/sun/java2d/Trace.h/c

   Thanks,
     Dmitri
