Magnus,

Do you still need this integrated? I can integrate the exact same changset to awt, 2d, and build forests if you want.

Can we remove these "empty JNI" classes from a list of "javah" classes somewhere so that we don't waste time generating the empty JNI headers? Good idea -- that's exactly what is being done in the new build system (the build-infra project)! :-) We added a new option to javac, which generates JNI headers automatically, if they are needed -- basically, if the class contains native methods *). So header generation is made always when needed and only when needed, quickly and as a part of normal compilation. Since these classes didn't have any native methods, the header files were not generated, and the compile of the native code failed since the #include pointed to non-exisiting files. *) Actually, sometimes classes with constants but without native methods are needed. In this case, the new annotation @GenerateNativeHeader is needed. /Magnus
