There is no new feature active in 1.6.0 in this regard.
Here is the diff: https://github.com/apache/maven-resolver/compare/maven-resolver-1.4.2...maven-resolver-1.6.0?w=1

Since I do not have access to your project, can you please try the following:
* Maven 3.7.0 with Resolver 1.4.2
* Maven 3.6.3 with Resolver 1.6.0
* If 3.7.0/1.4.2 does not affect the build, do a git bisect with 1.4.2 and 1.6.0.

Alternatively, provide the log output as configured here:
https://maven.apache.org/resolver-archives/resolver-LATEST/maven-resolver-synccontext-global/index.html#Debugging

In 1.6.0 there is even less synchronization because the TrackingFileManager does not lock anything anymore.

I will hold off vote completion until I get some analyzable data from you.

sorry about the fast finger,  my test shows a huge increase in build time

This cannot be. It has been superceded by
https://issues.apache.org/jira/browse/MRESOLVER-130. The
GlobalSyncContextFactory have been moved to a separate module, the
original behavior has been restored. I.e., this feature is not enabled
by default.

Are you certain that you don't have leftovers in ${maven.home}/lib/ext?

sadly, the build is not reproducible: reference build done with JDK 8
on
Windows, but Felix Maven Bundle Plugin is causing issues in generated
META-
INF/MANIFEST.MF (contains username, detailed JDK version, and order
or
Private
Package not reproducible): I'll have a look to check if recent
updates to
this
plugin can fix the issue...
