I'm building my J2SE workspace, say c:\work\mustang-workspace. My steps are:

  * cd c:\work\mustang-workspace\make
  * <path_to_build_script>\build.sh

After this my workspace is builded into c:\work\mustang-workspace\build (or any other folfer if specified explicitly). Then I try to re-build a part of the workspace that is related to windows-related AWT Java classes and native files. I do the following:

  * cd c:\work\mustang-workspace\make\sun\awt
  * <path_to_build_script>\build.sh clean
  * <path_to_build_script>\build.sh

I expect that all the AWT windows-related classes are removed and then builded again. However I'm receiving an error message:

# Running javac:
c:\work\mustang.b55\bin\javac ... -source 1.5 -target 6 @c:\work\mustang-workspace\build\tmp\sun\sun.awt\awt\.classes.list

symbol : class DebugHelper
location: package sun.awt
import sun.awt.DebugHelper;
              ^

Many other errors caused by missing sun.awt.DebugHelper class are generated. That is wrong, sun.awt.DebugHelper class should be built from make/sun/awt directory as well as it is built from from make/java/awt now.
