The exception was observed in the MCOMPILER-170 integration test of Maven Compiler Plugin, which launches Maven with the -T4 option. Relevant stack trace was:

Caused by: java.util.ConcurrentModificationException
    at java.util.HashMap.computeIfAbsent(HashMap.java:1230)
    at org.apache.maven.impl.DefaultDependencyResolver.moduleCache(DefaultDependencyResolver:98)

This exception occurs with Maven 4.0.0-RC-5 but did not occurred with RC-4, I'm not sure why.

The exception was observed in the integration tests of Maven Compiler Plugin when Maven is executed with the `-T4` option.
