Usually tests which are persisting to a database?

I’ve recently had this problem and I managed to solve it by not forking the batchtest task, and instead forking the junit target and setting the forkmode attribute to once, like so:

<junit printsummary="true" fork="yes" forkmode="once">
<batchtest todir="${tmp}">
</batchtest>
</junit>
