> The order dependent flakiness was detected when running multiple test
> classes. The polluter that caused the flakiness in AttachmentUtilTest.java
> was the test class CachedOutputStreamTest.java. In AttachmentUtilTest, there
> were multiple tests that used Mockito.spy() to verify the behavior of
> CachedOutputStream object. In those tests, the spy CachedOutputStream object
> "cos" was generated (CachedOutputStream cos = spy(CachedOutputStream.class)).
> Then after this, there was a line verify(cos).setThreshold(102400L).
> Therefore, after the cos being initialized, we need to make sure the
> setThreshold has been called once. However, it doens't execute as expected,
> and the root cause is that the threshold is not provided when calling
> testSetStreamedAttachmentProperties() method and the thresholdSysPropSet (the
> boolean that indicated whether the default threshold has been set or not) has
> been set to true when we run the CachedOutputStreamTest.java. Inside the
> CachedOutputStreamTest.java, the unit test
> testUseSysPropsWithAttachmentDeserializer() called the
> AttachmentUtil.setStreamedAttachmentProperties(message, cache), so the
> thresholdSysPropSet has been set to true then. Therefore, if we run
> CachedOutputStreamTest.java before running the AttachmentUtilTest.java, the
> verify(cos).setThreshold(102400L) statement will lead to the error message
> Wanted but not invoked:
> cachedOutputStream.setThreshold(102400L);
> -> at
> org.apache.cxf.attachment.AttachmentUtilTest.bigIntAsAttachmentMaxSize(AttachmentUtilTest.java:279)
