Dmitriy Neretin commented on LOG4J2-1243: ----------------------------------------- Hi [~ralph.go...@dslextreme.com], Sorry your fix didn't solve the problem. The problem itself was not the resolution of the default value, but wrong string replacement in the StrSubstitutor line: 989 -> buf.replace(startPos, endPos, varValue); > Faulty placeholder substitution in config xml > --------------------------------------------- > > Key: LOG4J2-1243 > URL: https://issues.apache.org/jira/browse/LOG4J2-1243 > Project: Log4j 2 > Issue Type: Bug > Components: Lookups > Affects Versions: 2.5 > Environment: JDK 8 > Reporter: Veit Guna > Assignee: Ralph Goers > Fix For: 2.8 > > > I'm using log4j 2.5 in a REST service. > There I would like to use the placeholder substitution to allow configuration > of the log location. > I tried this: > {code:xml} > <Properties> > <!-- sets the path for log4j logs: > 1. check whether java system property myapp.logs is set.
