Delegate security manager calls

JUnit5 System Extensions 1.2.0, released 2021-04-26

Summary

When trapping System.exit calls, the ExitGuardSecurityManager now doesn't simply replace an existing security manager anymore. Instead it uses the existing one as a delegate for all checks except the exit check.

This way applications that require a security manager don't change their behavior.

Update of the release letter 2021-05-02:
This version actually contains a breaking change that we overlooked: from this release on only Java 11 and above are supported.

Features

• #23: Delegate security manager calls to the original security manager

Refactoring

• #21: Migrate to Maven Central

Allow muting System.out / System.err

To mute the output (i.e. don't forward output to System.out / System.err) call stream.captureMuted() instead of stream.capture(). This can be useful to speed up unit tests.
