Project: Maven Shared Components

CommandLineUtils now creates Threads with default names, like Thread-1
I noticed it in one of thread-dump for hang maven build

It would be nice to set names for threads created by CommandLineUtils
{code}
final StreamFeeder inputFeeder = systemIn != null ? new StreamFeeder(
systemIn, p.getOutputStream() ) : null;
inputFeeder.setName("StreamFeeder-systemIn-process-" + p);
final StreamPumper outputPumper = new StreamPumper( p.getInputStream(),
systemOut );
inputFeeder.setName("StreamPumper-systemOut-process-" + p);
final StreamPumper errorPumper = new StreamPumper( p.getErrorStream(),
systemErr );
errorPumper.setName("StreamPumper-systemOut-process-" + p);
{code}
