> Found when testing release candidate 4 of 2.2.2.  Here's the text of an email I wrote.  Adam responded that it's probably a bug.

> I was just testing CVD for the next release, and tried
> out the new performance report feature.  Internally, this
> uses the ProcessTrace feature of AnalysisEngine.process().
> It seems that if the process() call returns very quickly,
> i.e., in 0ms according to the Java timer, no ProcessTrace
> sub-events are recorded.  For example, I'm running the
> tagger, and here's some output I get:
> This one looks fine, as expected:
> 3/27/08 4:29:52 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
> Component Name: HmmTaggerTAE
> Event Type: Analysis
> Duration: 2078ms (100%)
> Sub-events:
>     Component Name: WhitespaceTokenizer
>     Event Type: Analysis
>     Duration: 265ms (12.75%)
>     Component Name: Hidden Markov Model - Part of Speech Tagger
>     Event Type: Analysis
>     Duration: 1813ms (87.25%)
>     Component Name: Fixed Flow Controller
>     Event Type: Analysis
>     Duration: 0ms (0%)
> Next one seems to have lost the tagger:
> 3/27/08 4:30:08 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
> Component Name: HmmTaggerTAE
> Event Type: Analysis
> Duration: 16ms (100%)
> Sub-events:
>     Component Name: WhitespaceTokenizer
>     Event Type: Analysis
>     Duration: 16ms (100%)
>     Component Name: Fixed Flow Controller
>     Event Type: Analysis
>     Duration: 0ms (0%)
> Finally, this one only has the flow controller:
> 3/27/08 4:30:19 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
> Component Name: HmmTaggerTAE
> Event Type: Analysis
> Duration: 0ms
> Sub-events:
>     Component Name: Fixed Flow Controller
>     Event Type: Analysis
>     Duration: 0ms
> Looking at this in the debugger, there are no subevents
> there, so it's not a problem with the printing.
> Is this expected, or is it a bug?  Seems to me it is a bug,
> but I'm not sure from the documentation.
