Fix flush problem with integration of commons-logging output ------------------------------------------------------------ Key: JGRP-1796 URL: https://issues.jboss.org/browse/JGRP-1796 Project: JGroups Issue Type: Bug Affects Versions: 3.2.13 Reporter: Richard Achmatowicz Assignee: Richard Achmatowicz Priority: Minor Fix For: 3.2.13, 3.3.6, 3.5 The commons-logging output which appears in test case output files does not have line termination processed correctly. We end up with text like this: {noformat} 120665 [TRACE] GMS: - A: no initial members discovered: creating group as first member120666 [DEBUG] GMS: - A: installing view [A|0] [A]120666 [DEBUG] GMS: - created group (first member). My view is [A|0], impl is org.jgroups.protocols.pbcast.CoordGmsImpl {noformat} This makes reading the logging output hard to read. We want it to look like this: {noformat} 120665 [TRACE] GMS: - A: no initial members discovered: creating group as first member 120666 [DEBUG] GMS: - A: installing view [A|0] [A] 120666 [DEBUG] GMS: - created group (first member). My view is [A|0], impl is org.jgroups.protocols.pbcast.CoordGmsImpl {noformat} Th solution is to implement flush() as a method which simply appends a null string with CR/LF applied as well to the current collected sysout and syserr.
