Description
It would make sense if javac could generate native headers for classes containing native methods.
Comments
Suggested text for release notes: javac now provides the ability to generate native headers as needed. This removes the need to run the javah tool as a separate step in the build pipeline. The feature is enabled in javac by using the new -h option, which is used to specify a directory in which the header files should be written. Header files will be generated for any class which has either native methods, or constant fields annotated with a new annotation of type java.lang.annotation.Native.

EVALUATION This could be enabled by a new "output directory" option, -h. In addition, some minor changes to javax.tools would be desirable 1. new StandardLocation NATIVE_HEADER_OUTPUT 2. new annotation javax.tools.annotation.GenerateNativeHeaders The latter is to annotate classes for which a native header should be generated but which do not contain any native methods. This might be for native code to access public static final fields defined in a Java source file.
