Chris Douglas updated MAPREDUCE-1038:
-------------------------------------

    Attachment: M1038-1.patch

{noformat}
ant test -Dtestcase=TestConfiguration # Observe that weaving does not occur.
touch src/java/org/apache/hadoop/mapred/JobClient.java # "change" a MapReduce 
file
ant test -Dtestcase=TestConfiguration # Observe that weaving does not occur.
{noformat}

I don't think Hudson runs a clean before testing the patched build. This means 
that the Mumak tests would be run against the trunk version, rather than the 
patched version.

The aspects *should* be re-weaved if the core classes are modified.

> Mumak's compile-aspects target weaves aspects even though there are no 
> changes to the Mumak's sources

> This is particularly time consuming and is the bottle neck even for a simple 
> ant build. In the case where no files have been updated in Mumak, there is no 
> reason to recompile sources along with the aspects. compile-aspects should 
> skip this step in these cases.
