Which VM did you compile this with? It appears that trax is not kicking in for some reason, and it falls back to xslp, which doesn't work. I cannot reproduce this with 1.4-compliant VMs on x86, at least.
As agreed, I close this bug for now. Reopen if you see it again.
I had this bug too. The solution for me was to emerge ant-tasks.
