> Random failures in multiproject poms: cobertura can't read the .ser file
> ------------------------------------------------------------------------
>
> Key: MCOBERTURA-56
> URL: http://jira.codehaus.org/browse/MCOBERTURA-56
> Project: Maven 2.x Cobertura Plugin
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: fabrizio giustina
> Fix For: 2.5
>
>
> 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.
> [INFO] Cobertura 1.8 - GNU GPL License (NO WARRANTY) - See COPYRIGHT file
> Cobertura: Error reading file D:\myapp\target\cobertura\cobertura.ser: null
