Hi folks, We've had a recent PR to add "jdk.internal" to the list of packages we remove when sanitizing stacktraces:
https://github.com/apache/groovy/pull/1727 We've also had a much earlier request to filter less aggressively, see: https://github.com/apache/groovy/pull/256 https://issues.apache.org/jira/browse/GROOVY-7756 PR#1727 looks good to me but it seems worthwhile to consider both requests if we are going to make a change. Current list: groovy., org.codehaus.groovy., java., javax., sun., gjdk.groovy. Suggested by #1727: groovy., org.codehaus.groovy., java., javax., sun., gjdk.groovy., jdk.internal Suggested by #256: groovy., org.codehaus.groovy., java.lang.reflect., sun.reflect., gjdk.groovy. If we were going to include (most of) "java", then there is an argument that you should include "groovy" as well. My current thinking is something like below might work: Suggestion: org.codehaus.groovy., org.apache.groovy, java.lang.reflect, sun., gjdk.groovy., jdk.internal. The original thinking behind excluding "java." was that if you had a script with e.g. Strings and Lists, you didn't really need to know whether you had Java implemented data types or something supplied by Groovy. While this is still a worthwhile goal, in reality most folks need to know those datatypes pretty quickly, so hiding them away isn't super beneficial. I also discovered that Grails uses a list something like this: "org.codehaus.groovy.runtime.", "org.codehaus.groovy.reflection.", "org.codehaus.groovy.ast.", "org.springframework.web.filter", "org.springframework.boot.actuate", "org.mortbay.", "groovy.lang.", "org.apache.catalina.", "org.apache.coyote.", "org.apache.tomcat.", "net.sf.cglib.proxy.", "sun.", "java.lang.reflect.", "org.springframework.boot.devtools.", "org.springsource.loaded.", "com.opensymphony.", "javax.servlet." In terms of branches, I was thinking of Groovy 5 only and probably back-ported to 4. And just a reminder, there is a "groovy.sanitized.stacktraces" system property, so folks can change this if they really want. What do others think? Cheers, Paul.
