      Description

      After updating to Maven 3.5.2 we noticed increased build times in our scheduled Nightly Builds. The logs schow gaps of 10-15 minutes where the build just hangs.

      Our Build reactor contains 154 modules and we are running multithreaded builds (-T 4)

      The attached threaddump file was taken from a hanging build on a developer machine running 'clean install' goals. The CI Server runs the same build but with 'clean deploy'.
