Release Note: Passing Originating Elements From Filer to JavaFileManager

The `javax.tools.JavaFileManager` has been extended with two new methods, `getJavaFileForOutputForOriginatingFiles` and `getFileForOutputForOriginatingFiles`, that are used to create new files with specified originating files. The `Filer` uses these methods when creating new files (with `Filer.createSourceFile`, `Filer.createClassFile`, `Filer.createResource`) in order to pass along the files containing the _originating elements_.
