test/org/apache/catalina/tribes/group/TestGroupChannelMemberArrival.java
Author: kkolinko

New Revision: 1177053
URL: http://svn.apache.org/viewvc?rev=1177053&view=rev
Log:
Merged revision 1177050 from tomcat/trunk:
Improve TestGroupChannelMemberArrival
1. Add synchronization when accessing TestMbrListener.members.
This should fix the failures observed by Gump.
2. Remove unused method #clear().
3. Improve messages printed to System.out during the test
4. Print messages when memberAdded()/memberDisappeared() performed no work.
