Cannot restore previous console. This is not implemented yet

I seeing tests failing (but not all) with the following exception

Caused by: java.lang.UnsupportedOperationException: Cannot restore previous console. This is not implemented yet.
	at org.gradle.internal.logging.sink.OutputEventRenderer.restore(OutputEventRenderer.java:106)

which comes roughtly from the area of the following code

github.com

gradle/gradle/blob/aa098f75eb356c273df286c665bb941ce6e914e1/subprojects/logging/src/main/java/org/gradle/internal/logging/sink/OutputEventRenderer.java#L93




@Override
public Snapshot snapshot() {
    synchronized (lock) {
        // Currently only snapshot the console output listener. Should snapshot all output listeners, and cleanup in restore()
        return new SnapshotImpl(logLevel.get(), console);
    }
}


@Override
public void restore(Snapshot state) {
    synchronized (lock) {
        SnapshotImpl snapshot = (SnapshotImpl) state;
        if (snapshot.logLevel != logLevel.get()) {
            configure(snapshot.logLevel);
        }


        // TODO - also close console when it is replaced
        if (snapshot.console != console) {
            if (snapshot.console == null) {
                removeChain(console);

The question is what would be the cause of it. I have an test listener registered which captures output, but it is pretty simple.
