Compiling src/jdk.incubator.jpackage/windows/classes/jdk/incubator/jpackage/internal/WinMsiBundler.java with the Eclipse compiler (EC4J), I get errors that some of the statically imported symbols are ambiguous. This comes because WindowsBundlerParam extends StandardBundlerParam and the symbols of both classes are imported with *.

While I'm not sure whether this can be considered a bug in EC4J or in javac, I think this can easily be helped by simply cleaning up the import statements in the code.
