Ian Springer commented on MNG-3756:
-----------------------------------
Sure, it looks like the key is indeed that is has to be within a profile. Also,
that profile needs to be activated from the command line, rather than via
activeByDefault. Run the attached pom as follows:
mvn validate -P test
This should result in mvn hanging as follows:
"main" prio=6 tid=0x002a6000 nid=0x1d90 runnable [0x0090f000..0x0090fe54]
