Jenkins: 1.627
Matrix Project Plugin: 1.6
The problem reported in https://issues.jenkins-ci.org/browse/JENKINS-23902 (Matrix parent takes executor slot and blocks children) is still occuring.
I have 4 build executors and 4 (or more) jobs should be started by build triggers with the option "Block until the triggered projects finish their builds" set.
This results in 4 parent matrix jobs filling up the build executors so no actual build jobs can be started leading to a dead lock. Only killing some of these parent jobs results in the start of the actuall build jobs.

JENKINS-12290 Deadlock/Lockup when using "trigger/call builds on other projects" and "Block until the triggered projects finish their builds" is used with only 1 executor

This is caused by the current behavior of parameterized-trigger-plugin. It is not the matrix parent job which blocks an executor but the child job which should trigger other builds with parameters and wait for the completion.
