Chris M. Hostetter commented on SOLR-14099:
-------------------------------------------

SOLR-13662 added {{@LogLevel("org.apache=INFO")}} to {{PackageManagerCLITest}} 
and since that time, we've seen a big uptick in failures from 
{{LoggingHandlerTest.testLogLevelHandlerOutput}} which tries to assert that the 
level of the {{"org.apache"}} handler (in default solr operation) should be 
reported as {{null}} ...

...the only commonality in all of these jenkins failures is that 
{{PackageManagerCLITest}} had previously run in the same JVM.

This is trivially to reproduce locally when that 
{{@LogLevel("org.apache=INFO")}} annotation is in place when 
{{PackageManagerCLITest}} ...

...but both tests pass just fine if the annotation is removed

Something is clearly wrong with {{@LogLevel}}

> @LogLevel annotation not properly reseting after end of test (causes 
> LoggingHandlerTest.testLogLevelHandlerOutput failures)
