Intermittent Error reading cobertura.ser: illegal handle value or null
----------------------------------------------------------------------
Key: MCOBERTURA-91
URL: http://jira.codehaus.org/browse/MCOBERTURA-91
Project: Maven 2.x Cobertura Plugin
Issue Type: Bug
Affects Versions: 2.2
Environment: Linux RHEL 4, maven 2.0.9, surefire 2.4.1
Reporter: Lou S
When I run the cobertura 2.2 plugin from Windows, the report is always
generated using the site goal. However, when I promote this to run on our CI
server (which is Linux), I get the following stacktrace about 70% of the time:
{code}

I've hardcode the JVM for both surefire and cobertura as well as adding
-Dnet.sourceforge.cobertura.datafile=/local/mnt/cruisecontrol/projects/PCNRequestApproval/PCNRequestApprovalWeb/target/cobertura/cobertura.ser,
but that only seems to help some of the time.
