---------------------------------

             Summary: Intermittent java.lang.IllegalStateException - entry has not been leased from this pool
                 Key: MNG-7012
                 URL: https://issues.apache.org/jira/browse/MNG-7012
             Project: Maven
          Issue Type: Bug
          Components: Artifacts and Repositories
    Affects Versions: 3.6.0
         Environment: Docker (debian:buster as the parent)
            Reporter: Frank Rachel


We are sporadically getting this error:
{code:java}
2020:11:03-02:39:51 [WARNING] Failed to load provider from: org.codehaus.gmaven.runtime.loader.artifact.ArtifactProviderLoader@46256128
org.apache.maven.artifact.resolver.ArtifactResolutionException: Could not transfer artifact jline:jline:jar:0.9.94 from/to internal-nexus (http://ml-pecb-dk01.alipacn.com:50005/repository/alip-repo/): Entry [id:541][route:{}->http://ml-pecb-dk01.alipacn.com:50005][state:null] has not been leased from this pool
jline:jline:jar:0.9.94{code}
in our builds when download artifact from our Nexus repo. This happened under 3.5.4, and stil under 3.6.0 (we can't yet upgrade to 3.6.3, but will be able to soon).

It's not always on the same artifact as the exception. This seems to happen for about 10% of our builds.. we just re-run it and most of the times it then works.

It also didn't seem to happen when we were using Artifactory (an old version) instead of Nexus, though not sure that's related since a lot of other things changed at the same time.
