It appears that there is an intermittent failure in the javafx.concurrent.ServiceLifecycleTest cancelCalledFromOnFailed test. I hadn't seen it before today, but two different test runs (both on the same Linux system, our Hudson Linux test slave) both failed last night with this test failure:

javafx.concurrent.ServiceLifecycleTest > cancelCalledFromOnFailed FAILED
    java.lang.AssertionError: expected:<FAILED> but was:<CANCELLED>
        at org.junit.Assert.fail(Assert.java:91)
        at org.junit.Assert.failNotEquals(Assert.java:645)
        at org.junit.Assert.assertEquals(Assert.java:126)
        at org.junit.Assert.assertEquals(Assert.java:145)
        at javafx.concurrent.ServiceLifecycleTest.cancelCalledFromOnFailed(ServiceLifecycleTest.java:1302)


Also on windows running pre-release jfx24
