Sorry guys, now I am android games developer and I have no time for JAVA [perhaps in the future].
PS: Code have some bugs for sure, I started learn java on it, if you are good in programming you can improve it on your own ;)
I am using JDK 1.7 and it works fine. First check your classpath in eclipse for wrong libs etc, if ok try to update JDK to 1.7, if still not works try to google (i have no idea). GL ;)
If you have problem, install jdk 1.7 and change project settings for jdk 1.7 ( Frozen is supporting JDK 1.7).
RMB on Project -> Properties -> Java Compiler:
it will be the fastest way for You.
Yes, like i sad, i reworked everything for jdk 1.7. It is mean you should change project settings for jdk 1.7 or rework the code in empty brackets: <> you should add for example:
JDK 1.7:
Map<Integer, TopField> tmpTopGatherersTable = new LinkedHashMap<>();
JDK 1.6:
Map<Integer, TopField> tmpTopGatherersTable = new LinkedHashMap<Integer, TopField>();
* find diffrence ;)
