    OS: Windows 8 x64
    Software: EMET 4.0.4854.22470 (Beta), Java 7

    I installed Java for a one-time task a few days ago. Yesterday, EMET shut down Java. I wasn't using Java at the time so I don't know why it was running. Anyway, I uninstalled Java. The errors are below. Is this a problem with EMET 4 Beta or did I really have an infection that was mitigated?

    Code:
    Application Name: C:\Program Files (x86)\Java\jre7\bin\javaw.exe
    Execution flow simulation check failed:

    Mine EMET is 4.0.4913.
    It's quite possible just incompatibility of the Java with "SimExecFlow" mitigation. Uncheck it for the Java.
    Did EMET popup when Java started? If yes then just uncheck the popup mitigations.
