Description

Tasks like exec:exec and surefire (testing) seem to receive an occasional interrupt signal, causing the test or task to fail. This only happens on multi-module projects (i.e. if I run it a module at a time, it works).

Here's an example stacktrace from exec:exec (I can try to reproduce the surefire one as well):

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Command execution failed.

Embedded error: Error while executing external command, process killed.
[INFO] ------------------------------------------------------------------------
