[ http://jira.qos.ch/browse/LBCORE-4?page=com.atlassian.jira.plugin.system.iss... ] Selen Schabenberger commented on LBCORE-4: ------------------------------------------ This issue is still reproducable in release 0.9.21 if the policy (FixedWindowRollingPolicy) is defined programmatically. FileNamePattern class is converting all backslashes to slashes in its contructor; therefore it is not possible to assign a file name pattern with an escaped percent sign. Is it a restriction or a bug?

The insertion of a percent symbol causes the Parser to crash ------------------------------------------------------------

Key: LBCORE-4 URL: http://jira.qos.ch/browse/LBCORE-4 Project: logback-core Issue Type: Bug Components: Pattern Affects Versions: unspecified Environment: Operating System: All Platform: All Reporter: Sébastien Pennec Assignee: Logback dev list Priority: Blocker

When inserting the percent char twice, so that it appears in the PatternLayout output, a number format exception is thrown. It does not prevent from using normally the PatternLayout. trace: ERROR in ch.qos.logback.core.joran.spi.Interpreter@131f71a - Exception in Action for tag <layout>8:14 java.lang.NumberFormatException: For input string: "% %" java.lang.NumberFormatException: For input string: "% %" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Integer.parseInt(Integer.java:447) at java.lang.Integer.parseInt(Integer.java:497) at ch.qos.logback.core.pattern.FormatInfo.valueOf(FormatInfo.java:70) at ch.qos.logback.core.pattern.parser.Parser.T(Parser.java:84) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:51) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.Eopt(Parser.java:107) at ch.qos.logback.core.pattern.parser.Parser.E(Parser.java:55) at ch.qos.logback.core.pattern.parser.Parser.parse(Parser.java:31) at ch.qos.logback.core.pattern.PatternLayoutBase.start(PatternLayoutBase.java:76) at ch.qos.logback.core.joran.action.AbstractLayoutAction.end(AbstractLayoutAction.java:75) at ch.qos.logback.core.joran.spi.Interpreter.callEndAction(Interpreter.java:289) at ch.qos.logback.core.joran.spi.Interpreter.endElement(Interpreter.java:152) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:633) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanEndElement(XMLNSDocumentScannerImpl.java:719) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1685) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:764) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:148) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1242) at javax.xml.parsers.SAXParser.parse(SAXParser.java:375) at ch.qos.logback.core.joran.JoranConfiguratorBase.doConfigure(JoranConfiguratorBase.java:125) at ch.qos.logback.core.joran.JoranConfiguratorBase.doConfigure(JoranConfiguratorBase.java:101) at ch.qos.logback.core.joran.JoranConfiguratorBase.doConfigure(JoranConfiguratorBase.java:84) at ch.qos.logback.core.joran.JoranConfiguratorBase.doConfigure(JoranConfiguratorBase.java:77) at mainPackage.ConfigTester.main(ConfigTester.java:21)
