Description

When generating the site on a complex multiproject build, sometimes the cobertura report fails reporting an error from cobertura:
Cobertura: Error reading file D:\myapp\target\cobertura\cobertura.ser: null

The error doesn't happen all the times (50% of the times), but it definitively happens. Cobertura.ser IS in place and is found by Cobertura.
The error comes from an IOException in Cobertura itself (which is hidden). After adding some more debug to the cobertura code this is what I get:

[INFO] Generate "Cobertura Test Coverage" report.
