       I made the proposed experiment.  My goal is to build debug 
version of JDK that does not take a long time to rebuild.

      I put  1.7.0_07-b32 to PATH variable so
    -------------------------------------------------------------------
     $ java -version
     java version "1.7.0_07"
     Java(TM) SE Runtime Environment (build 1.7.0_07-b32)
     Java HotSpot(TM) Client VM (build 23.3-b01, mixed mode)
    ------------------------------------------------------------------

     I used http://hg.openjdk.java.net/jdk8/jdk8 repository.
     Each time I used the clean repository.

    1) Build only debug version
            configure-arguments: --with-target-bits=32 --enable-debug

   ----- Build times -------
Start 2013-02-15 16:22:41
End   2013-02-15 16:40:01
00:00:45 corba
00:04:54 hotspot
00:00:38 jaxp
00:00:56 jaxws
00:09:18 jdk
00:00:41 langtools
00:17:20 TOTAL
-------------------------

   Build is successful.

2a) Build debug version with sjava (the same JDK in PATH, the same 
repository)
    configure-arguments: --with-target-bits=32 --enable-debug 
--enable-sjavac

100 errors
3 warnings

2b) Build debug version with sjava (the same JDK in PATH, the same 
repository)
    configure-arguments: --with-target-bits=32 --enable-debug 
--enable-sjavac

    with the suggested patch that  checks "os.name" variable:

              for (;;) {
                  String l = in.readLine();
                  if (l == null)

  Could you check this scenario (--with-target-bits=32 --enable-debug 
--enable-sjavac) on your side?


  Thanks,
  Alexandr.
