If you really want to hunt down java dir warnings, try using
contrib/warn_summary.

%warn_summary -java output.log

Counting warnings in the gcc/java subdirectory,
there are 13 warnings in stage3 of this bootstrap.
 
Number of warnings per file:
   6 gcc/java/jcf-parse.c
   3 gcc/java/jvspec.c
   2 gcc/java/jcf-io.c
   1 gcc/java/verify.c
   1 gcc/java/mangle.c
 
Number of warning types:
   5 comparison between pointer and integer
   4 `???' might be used uninitialized in this function
   2 comparison between signed and unsigned
   1 string length `???' is greater than the length `???' ISO C89 compilers are required to support
   1 initialization makes pointer from integer without a cast
