I'm getting the following stack trace with Java 7 (but no with Java

Comment 1 Mark Thomas 2013-09-12 18:00:57 UTC
java.util.concurrent.ConcurrentHashMap$KeySetView doesn't exist in Java 7. I'm not sure how but you appear to have a Java 8 artifact involved here. Whatever is going on, it is an environmental issue on your system.
Comment 2 rstoyanchev 2013-09-12 18:37:38 UTC
Odd, because that is a JDK class and the issue occurs when I run with JDK 1.7.
Comment 3 Christopher Schultz 2013-09-12 20:00:28 UTC
Bug is INVALID, not FIXED.
When you run in Java 7 mode, something must be terribly wrong, because it looks like it's trying to use a Java 8 class. That's what makes your environment broken. Try re-installing the JRE?
