Summary: looping/race condition in Property/PropertyHelper
Product: Ant
Version: 1.7Alpha (nightly)
Platform: PC
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P1
Component: Core
AssignedTo: dev@ant.apache.org
ReportedBy: stevel@apache.org
As raised on ant-dev, the property evaluation code in SVN_HEAD is capable of
going in to an infinite loop, despite the stack checks that appear designed to
prevent exactly that. Marked as critical, as without a fix, Ant does not run to
completion on approximately 50% of my builds.

seems to, but let's leave it open for a while until I am more convinced all is
well. That's the trouble with any concurrency-related bug: hard to replicate,
and hard to verify that it is gone.
downgrading to regression, as it is no longer critical for me, marking as needinfo
