Processing 2.1 fails to compile all of its projects using JDK8 EA b119 error: The type java.util.Map$Entry cannot be resolved.

[Vicente-Arturo Romero-Zaldivar]

Hi Xerxes,

According to this description the bug was in eclipse's compiler, not in 
javac.

Thanks for your mail, I will close the bug as "not an issue".
