java.util.logging misbehavior when called from JRuby
----------------------------------------------------
Key: JRUBY-3628
URL: http://jira.codehaus.org/browse/JRUBY-3628
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Java Integration
Affects Versions: JRuby 1.2
Environment: Java 1.6, JRuby 1.2
Reporter: Morten Christensen
When calling Java's java.util.logging system within Jruby, the logger name is
wrongly set to "sun.reflect.NativeMethodAccessorImpl" instead of the logger
name specified by the call to Logger. Apart from making things difficult when
reading the log, this also cause the normal java log filters to malfunction
(i.e the log messages from jruby may not appear unless a special/default log
level is set to log sun.reflect also). This is a major problem with java/jruby
projects, as proper logging behavior is essential for production systems!
To reproduce try this under IRB:
log = java.util.logging.Logger.getLogger('com.test.xxx')
log.addHandler(java.util.logging.ConsoleHandler.new())
log.log(java.util.logging.Level::SEVERE, 'Logging from JRuby')
The correct result would be something like:
May 7, 2009 1:31:13 PM com.test.xx ???
SEVERE: Logging from JRuby
But JRuby 1.2 incorrectly writes:
May 7, 2009 1:31:13 PM sun.reflect.NativeMethodAccessorImpl invoke0
SEVERE: Logging from JRuby
