Subject Re: Strange, intermittent problem running the new models.company tests
Date Thu, 15 Feb 2007 20:27:03 GMT
I'm seeing an NPE Error in the test testBasicQueries 
(org.apache.openjpa.persistence.models.company.propertyaccess.TestProper 
tyCompanyModel)  when running mvn clean package.

I can send the error log if anyone would like to see it.
