[wildfly-dev] Java 8 API Warning

[Steve Ebersole]

I ran into issues with using Java 8 to run my build but targeting Java 7
for most artifacts.  I would highly suggest applying a solution based on
AnimalSniffer or supplying the Java 6/7 tools.jar for bootclasspath to
javac.  Helps catch these types of issues
