      Description

      (synopsis is provisional, until we figure out the root cause)

      Current tier1 on arm32 fails lots of floating point tests. I believe this group fails for the same reason: floating point math is broken.

      jdk/internal/math/FloatingDecimal/TestFloatingDecimal.java
      java/lang/Math/CubeRootTests.java
      java/lang/Math/HypotTests.java
      java/lang/StrictMath/HypotTests.java
      compiler/floatingpoint/TestFMA.java
      java/util/stream/test/org/openjdk/tests/java/util/stream/FlatMapOpTest.java
      java/util/stream/test/org/openjdk/tests/java/util/stream/SliceOpTest.java
      java/util/stream/test/org/openjdk/tests/java/util/stream/StreamBuilderTest.java

      Example failure:

      $ CONF=linux-arm-server-fastdebug make run-test TEST=java/lang/Math/HypotTests.java
