🎉 Major features and improvements

• Support for Java 17 (#322, #324) @basil

💥 Breaking changes

The addition of @{jenkins.addOpens} and @{jenkins.insaneHook} to argLine exposes a bug in IntelliJ IDEA. A patch has been proposed in JetBrains/intellij-community#1976. Pending the merge and release of this patch, IntelliJ IDEA users should work around the problem as follows:

1. Go to Settings > Build, Execution, Deployment > Build Tools > Maven > Running Tests.
2. Under "Pass to JUnit process [the] following maven-surefire-plugin and maven-failsafe-plugin settings", uncheck argLine.

Failure to work around the problem as described above will result in a could not open '{jenkins.addOpens}' failure when running tests in IntelliJ IDEA.
