svn commit: r698182 - /felix/trunk/shell.tui/src/main/java/org/apache/felix/shell/tui/Activator.java

[rickhall]

Author: rickhall
Date: Tue Sep 23 07:03:15 2008
New Revision: 698182

URL: http://svn.apache.org/viewvc?rev=698182&view=rev
Log:
Modified the input thread to look for null input lines, in which case it 
assumes that there is no standard input and exits. If we do not do this,
then the thread will enter a tight infinite loop. (FELIX-729)
