I'm on latest version `1.2.0`, see [this ](https://github.com/salesforce/grpc-java-contrib/blob/79aeea46a61b9f3d724a172ab29374931c02fa7c/jprotoc/jprotoc/src/main/java/com/salesforce/jprotoc/ProtocPlugin.java#L160)  The next call to `Files.createParentDirs(outFile);` at line `167` fails with ``` java.io.IOException: The filename, directory name, or volume label syntax is incorrect ```
