             Summary: IOException in aesh console initialization results in NPE
                 Key: WFLY-2009
                 URL: https://issues.jboss.org/browse/WFLY-2009
             Project: WildFly
          Issue Type: Bug
          Components: CLI
    Affects Versions: 8.0.0.Alpha4
            Reporter: Jan Martiska
            Assignee: Jan Martiska


In source file org.jboss.as.cli.impl.Console, method Factory.getConsole:
if the constructor call "new org.jboss.aesh.console.Console()" leads to an IOException, it is only logged and then ignored, always yielding a NullPointerException just a few lines later (console.addCompletion(new Completion() ...)

I think the IOException should rather be rethrown wrapped in a CliInitializationException, so the resulting exception will not lose track of why this happened. Allowing a NPE go out of the internals is a wrong approach.
