FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
When using a javax.annotation.processing.Filer.getResource() com.sun.tools.javac.processing.JavacFiler.getResource() always throws a FileNotFoundException due to using the javax.tools.JavaFileManager.getFileForInput() instead of getFileForOutput().

Here is a link to the change log where the it happened http://hg.openjdk.java.net/jdk7/jdk7/langtools/diff/f3323b1c65ee/src/share/classes/com/sun/tools/javac/processing/JavacFiler.java.

REGRESSION. Last worked in version 7


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Compile OpenJDK with the following change to com.sun.tools.javac.processing.JavacFiler.


    public FileObject getResource(JavaFileManager.Location location,
                                  CharSequence pkg,
                                  CharSequence relativeName) throws IOException {
        String strPkg = pkg.toString();
        if (strPkg.length() > 0)
            checkName(strPkg);

        // TODO: Only support reading resources in selected output
        // locations? Only allow reading of non-source, non-class
        // files from the supported input locations?
        //FileObject fileObject = fileManager.getFileForInput(location,
        // pkg.toString(),
        // relativeName.toString());
        FileObject fileObject = fileManager.getFileForOutput(location, pkg.toString(), relativeName.toString(), null);
        if (fileObject == null) {
            String name = (pkg.length() == 0)
                    ? relativeName.toString() : (pkg + "/" + relativeName);
            throw new FileNotFoundException(name);
        }

        // If the path was already opened for writing, throw an exception.
        checkFileReopening(fileObject, false);
        return new FilerInputFileObject(fileObject);
    }
