> can **not** be merged into the branch `patterns-stage-2`:
> The following file contains merge conflicts:
> 
> - src/jdk.compiler/share/classes/com/sun/tools/javac/parser/JavacParser.java
> 
> All Committers in this [project](https://openjdk.java.net/census#amber) have access to my [personal

> push the resulting merge commit to this pull request. The below commands should be run in a local clone of your
> [personal fork](https://wiki.openjdk.java.net/display/skara#Skara-Personalforks) of the
