Foilks, there is an issue HARMONY-5807, Apache Hadoop cannot compile on Harmony due to non-generic signature in concurrent package. The issue seems trivial to fix, but how should we handle it given this is external code?
FYI, JAPI report shows there are 3 issues in total [1]: interface java.util.concurrent.Delayed: implements java.lang.Comparable<java.util.concurrent.Delayed> in JDK_5.0, but implements raw java.lang.Comparable in Harmony_5.0 method java.util.concurrent.ConcurrentHashMap.clone(): throws java.lang.CloneNotSupportedException in JDK_5.0, but doesn't throw java.lang.CloneNotSupportedException in Harmony_5.0 method java.util.concurrent.PriorityBlockingQueue.comparator(): type java.util.Comparator<? super T> in JDK_5.0, but type java.util.Comparator in Harmony_5.0 [1] http://people.apache.org/~smishura/latest-harmony-japi.html#pkg_java_util_concurrent -- Alexey
