OutOfMemoryException at JUnitTestRunner.java:342
Summary: OutOfMemoryException at JUnitTestRunner.java:342
Product: Ant
Version: 1.6.2
Platform: All
OS/Version: Other
Status: NEW
Severity: Major
Priority: Other
Component: Optional Tasks
AssignedTo: dev@ant.apache.org
ReportedBy: skjones@avaya.com
I'm debugging a junit stress test, and set my logging Level to FINE. My test
starts outputting a TON to the console. The test is running from a forked JVM
using the junit tag's fork attribute="yes" and showoutput="yes".
Using hprof, I tracked it down to JUnitTestRunner's code which stores up all of
the task's stdErr and stdOut in a BYTE ARRAY, and then starts copying it all
over the place using a TeeOutputStream and ResultFormatters. Please update this
class so that it does not hold the task's entire output in memory.
As of today, this problem is present on the HEAD.
