What causes "Error saving report" error?

Hi

I am trying to generate the junit style test results using flex unit.

The error log is:

The error at the bottoms says it could not find the file TestCase1.xml, but I checked the reports folder and TEST-scheduledTaskSuite.tests.TestCase1.xml is indeed there.

I have a total of 14 tests and sometime there are two reports generated, sometimes 7, but it appears it is a timing issue as a random number of reports out of the 14 are generated each time.
