Hello Marc and Evgeny you may be right about the JDK bug.
I updated my JDK just to make sure it wasn't it, still had the problem. I managed to get the coverage by doing either of those 2 options : -- Pressing stop button in eclipse near the end of the run -- Addin a Thread.sleep(100000) in one test which gets interrupted ending up with 1 failing test but allowing me to get the coverage. so it's probably the racing condition of https://bugs.openjdk.java.net/browse/JDK-8154017 that happenned -- You received this message because you are subscribed to the Google Groups "JaCoCo and EclEmma Users" group.
