Messed up in the code somewhere probably. Even if eclipse isn't giving you an error.

Reminder for everyone to make sure that their JRE and JDK is on version 7. Java version 8 impacts massively and causes a NoSuchMethod Exception when you try to call the keySet() method(used in the progressAll method) with ConcurrentHashMaps.

How do you tell the difference between java 7 and java 8? xD
Click to expand...
In eclipse, go to your projects properties, select "Java Build Path" then select "Libraries". The bottom library should be "JRE System Library [java version here]". To tell the individual difference between the 2 would be impossible, as there are many differences.

OK, so I have java 8 installed, do i really have to remove java and install java 7, or can I just CODE in Java 7, instead.

you can code in java 7 instead.

Right Click your project and go to properties.

Then go to "Java Build Path" then > "Libraries".

Select "JRE System -blah blah blah-" and then Click "Edit".

Select Java8 from the drop down menu. If it isn't there, Google is your next bet.
