Richard S. Hall resolved FELIX-729.
-----------------------------------
Resolution: Fixed
Assignee: Richard S. Hall
I was not able to test this under windows, but I was able to recreate a similar
situation under Linux by redirecting stdin to /dev/null. As a result, I
modified Shell TUI to look for a null input line, in which case it now assumes
that there is no stdin and exits its thread's run() method.
Barend, I deployed a snapshot of ShellTUI 1.1.0 into the maven snapshot repo,
could you please test it to see if it solves the issue for you? If so, please
close this JIRA issue. Thanks.

> Key: FELIX-729
> URL: https://issues.apache.org/jira/browse/FELIX-729
> Project: Felix
> Issue Type: Bug
> Components: Shell
> Affects Versions: felix-1.0.4, felix-1.2.0
> Environment: Windows 2000 SP4, Windows Vista Enterprise, JDK 1.6
> Reporter: Barend Garvelink
> Assignee: Richard S. Hall
>
> I ran into this issue at work with Felix 1.0.4 on Win2k SP4 and reproduced it
> at home with Felix 1.2.1 on Vista Enterprise, both on JDK 1.6. I only
> discovered it by accident, as I normally use the console during development.
> I suspect the people reading this do, too :-).
> When using the javaw.exe launcher rather than the java.exe launcher,
> Felix-shell-TUI permanently draws 100% CPU (divide by the number of cores,
> home PC reports 50%). After removing shell-TUI from the autostart list, Felix
> can be run with the javaw launcher without issue, demonstrating that the
> problem originates from that bundle.
> Steps to reproduce:
> 1) unzip a fresh copy of Felix-1.2.1.zip
> 2) in the install dir, create two batch files: felix-console.bat and
> felix-noconsole.bat, one executes `java -Dfelix.cache.profile=consoletest
> -jar bin\felix.jar`, the other executes `javaw
> -Dfelix.cache.profile=consoletest -jar bin\felix.jar`
> 3) double-click either from Windows Explorer, note that when you run the
> "javaw" one, CPU shoots to 100% and stays there.
> Running them from within Windows Explorer isn't strictly necessary to
> reproduce the issue, the problem will also show when you start the batch file
> from the command line.
