public Object getInvokeSpecialHandle(Method m, Object receiver)
Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead

public Class[] getPluginDefaultGroovyMethods()
public Class[] getPluginStaticGroovyMethods()
public int getVersion()
Gives the version the plguin is made for
- Returns:
- 5 for jdk5, 6 for jdk6, 7 for jdk7 or higher
