source <(mvnd --completion bash) stopped working in 0.9.0

[ppalaga]

When issuing

source <(mvnd --completion bash)

the completion script appears in the console, but the completion is not sourced.

Similarly, when piping the output of --completion bahs to wc the count is zero

mvnd --completion bash | wc
[the whole completion script here]

      0       0       0

Workaround: adding 2>&1 makes it work:

mvnd --completion bash 2>&1 | wc
    358    1259   20910

The upgrade to JLine must be the cause. JLine and mvnd now better supports out and err streams.
I think the line

maven-mvnd/client/src/main/java-mvnd/org/mvndaemon/mvnd/client/DefaultClient.java

Line 223 in e10aecd

output.accept(Message.log(Completion.getCompletion(completionShell, parameters)));

should be changed to use Message.out(xxx) to force the usage of the output stream.
