-------------------------------------
Summary: CLI error on window resize on Linux(Wayland)
Key: KARAF-5406
URL: https://issues.apache.org/jira/browse/KARAF-5406
Project: Karaf
Issue Type: Bug
Environment: Fedora 26 with Wayland
JDK9
Karaf 4.1.2
Reporter: Paolo Antinori
Priority: Minor
This is interesting.
It looks like `jline` is not silenced to ignore UI events it doesn't expects.
If I minimize/maximize my Terminal, which corresponds to the linux package
`terminator-1.91-2.fc26.noarch`
I get this error spitted in the CLI console:
```
