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]

Processing internally used the Eclipse ecj compiler:
The following code and command can reproduce the issue in combination with JDK 8 b119:

$ cat HelloWorld.java
import java.util.HashMap;

public class HelloWorld {
    public static void main(String[] args) {
      System.out.println("Hello World!");
    }
}

#download the eclipse ecj version used internally by processing.
wget https://github.com/processing/processing/raw/master/java/mode/ecj.jar

tar zxvf jdk-8-ea-bin-b119-linux-i586-05_dec_2013.tar.gz

./jdk1.8.0/bin/java -jar ecj.jar -source 1.6 -classpath . -nowarn HelloWorld.java
Annotation processing got disabled, since it requires a 1.6 compliant JVM
----------
1. ERROR in HelloWorld.java (at line 1)
	import java.util.HashMap;
	^
The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files
----------
1 problem (1 error)



# The compilation succeed if ecj.jar is invoked without the -source 1.6 argument:
./jdk1.8.0/bin/java -jar ecj.jar -classpath . -nowarn HelloWorld.java
./jdk1.8.0/bin/java HelloWorld
Hello World!

I do not have any account at bugs.openjdk.java.net that I can use to update this bug,
feel free to attach the information above to the bug.
