Windows 7 64 bit

Please provide any additional information below.
Compile works with java7. I think the issue happens because in java8 there is a 
new remove(Object key, Object value) method in java.util.Map , and its return 
value type crushes with gov.nist.core.MultiMap's return value type. I think the 
2 methods internal functionality is different, so a rename/refactor might be 
required in gov.nist.core.MultiMap.
