Logback throws NP Exception when trying to use groovy configuration file. ------------------------------------------------------------------------- Key: LBCLASSIC-270 URL: http://jira.qos.ch/browse/LBCLASSIC-270 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.9.29 Environment: Has been verifed on both Linux and Windows and Oracle "standard" JVM and Oracle JRockit. slf4j-api.jar logback-classic.jar and logback-core.jar should be in %JRE_HOME%/lib/endorsed folder Start applikation with -Dlogback.configurationFile=<somewhere>/logback.groovy Reporter: Nicolai Marck Ødum Assignee: Logback dev list If logback jars (logback-claaic and logback-core) are located in endorsed libraries ( -Djava.endorsed.dirs) its not possible to use a logback configuration url that ends with groovy. This is because of line 23 in ch.qos.logback.classic.util.EnvUtil ClassLoader classLoader = EnvUtil.class.getClassLoader(); witch return null if called from endorsed libraries. It should work if you change it to ClassLoader classLoader = EnvUtil.class.getClassLoader(); if (classLoader == null) classLoader = ClassLoader.getSystemClassLoader(); I have not been able to verify this fix since I am not able to build logback :-( -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
