Oscar Palladino created LOGBACK-1459: ---------------------------------------- Summary: Message replace won't work when checking a regex text inside another exception Key: LOGBACK-1459 URL: https://jira.qos.ch/browse/LOGBACK-1459 Project: logback Issue Type: Bug Components: logback-core Affects Versions: 1.2.3 Environment: Windows 10 Spring boot 2.1.3 Spring ingegration 5.1.3 Reporter: Oscar Palladino Assignee: Logback dev list Hello, I am trying to mask a token in the logs, and in order to do so i am using this pattern : {code:java} <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] - ${PID:-????} %5p [%t] --- %c{1}: %replace(%msg){'Bearer\s[0-9a-zA-Z_\.\n\r-]{798}','***'}%n</pattern> {code} This pattern works well but when said token is to be found inside another exception (nested). In that case the regex expression fails to replace it. This happens to me in the class MessagePublishingErrorHandler of spring integration when printing a stacktrace that at the bottom contains the message with the header. Could you please have a look at that? Thanks -- This message was sent by Atlassian JIRA (v7.3.1#73012)
