Description

The BlockingCallMonitoringThreadPool modifies the core/maximum pool size of an underlying executor. It always first modifies the core size, and then the maximum size. When increasing the pool size it thus follows that core size at one point exceeds the maximum. This is fine on java 8, but no longer allowed on Java 9.
