https://github.com/apache/tomcat/commit/996bd6194952114ec5b0da3010b117c6797d0d2b#diff-28c2be466490f0a2d3b42c81c95168050789a60f4719027adb47b2ff99f636ed
More specifically, calling "addServiced" before "check" now has collateral
effects that cause unexpected effects. Now, the "check" method implicitly calls
"tryAddServiced", and if the method returns "false", it doesn't call
"checkResources". So, calling "addServiced" before "check" will cause "check"
to not execute "checkResources".
If pre-8.5.64 behavior is no longer acceptable for this API, maybe these
changes should be documented in
http://tomcat.apache.org/migration-85.html#Upgrading_8.5.x.
