Hi Jessye! Looks good, but the testClearAllTransforms tests should really validate that the byte code no longer contains the events. Also, since test execution can't be known, the clear all transforms test should first attempt to transform. Also - the JMX API should really, really not return (potentially serialize) classes, but I will open a separate issue for this, as it is not related to this PR.
