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

[Xerxes Rånby]

This have been fixed in eclipse ecj upstrem.

Updating java/mode/ecj.jar inside Processing 2.1
to eclipse ecj version 4.3.1
http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/R-4.3.1-201309111000/ecj-4.3.1.jar
fixes this issue.

Cheers
Xerxes
