http://issues.apache.org/bugzilla/show_bug.cgi?id=43438 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: [EMAIL PROTECTED] 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.
