ejb-xa-recovery folder is not cleaned up after testsuite

After the basic testsuite is run, there remains a ejb-xa-recovery folder in testsuite/integration/basic that is not properly cleaned up.

I grepped the testsuite for ejb-xa-recovery but could not find a match.
I suspect that this folder is created by Narayan as it deals with XA recovery.

This folder contains a single file named 20005_00000000000000000000ffff7f0000010000f9965b2237980000003b31_00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 whose content is:
