Kristian Rosenvold commented on SUREFIRE-710:
---------------------------------------------
Would you happen to be running with forkedProcessTimeoutInSeconds set to
something non-zero when this happens ?
This actually seems to be just another side-effect of SUREFIRE-690
(PLXUTILS-138), which is causing threads reading IO from the process to be
creeping in to places they should after a forked process has timed out.
PLXUTILS-138 and plexus-utils 2.0.7 will be out soon which should fix this.
Would this fit your environment/problem ?
