> Support for ConcurrentHashMaps with non-string keys seems to be broken when 1.8 version of Java is used because the newer ConcurrentHashMap uses the names "key" and "val" instead of "key" and "values" for its Map.Entry class.
> [HashEntry in 1.7|http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/util/concurrent/ConcurrentHashMap.java#218]
> [MapEntry in 1.8|http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/8u40-b25/java/util/concurrent/ConcurrentHashMap.java?av=h#3468]
> Hence avro-code that assumes the presence of key/value breaks.
> ([ReflectData.java:L434-L443|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/reflect/ReflectData.java#L434-L443])
> Run the attached test to see the same.
