[ https://issues.jboss.org/browse/JBWEB-219?page=com.atlassian.jira.plugin.... ] Kamil Prochazka commented on JBWEB-219: --------------------------------------- I came across this issue too with my log4j ConversionPattern. Something like this: log4j.appender.file.layout.ConversionPattern=%d{ISO8601} %-5p %c{1} - %m%n I just replaced %m%n with %m\n. Works fine on windows machine. Suppose this issue is related to OS new line delimiter. -- This message is automatically generated by JIRA.
