Subject [jira] [Commented] (RIVER-416) The com.sun.jini.logging.Levels class produces a RuntimeException with the latest version of Java
Date Wed, 06 Feb 2013 15:21:12 GMT

    [ https://issues.apache.org/jira/browse/RIVER-416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13572482#comment-13572482

Dennis Reedy commented on RIVER-416:
------------------------------------

Inn looking at Level, a Level is equal to another Level if they have the same integer value.
The readResolve() for Level is:

{code}
// Serialization magic to prevent "doppelgangers".
// This is a peformance optimization.
private Object readResolve() {
    synchronized (Level.class) {
    for (int i = 0; i < known.size(); i++) {
	Level other = (Level) known.get(i);
	if (this.name.equals(other.name) && this.value == other.value
		&& (this.resourceBundleName == other.resourceBundleName ||
		    (this.resourceBundleName != null &&
		    this.resourceBundleName.equals(other.resourceBundleName)))) {
	    return other;
	}
    }
    // Woops.  Whoever sent us this object knows 
    // about a new log level.  Add it to our list.
    known.add(this);
    return this;
    }
}    
{code}

I'm not seeing why we need to add a different readResolve()?

> The com.sun.jini.logging.Levels class produces a RuntimeException with the latest version
of Java (both 1.6 and 1.7). The issue surrounds creation of custom java.util.logging.Level.
The current implementation uses a ClassReplacingObjectOutputStream and the LevelData approach.
By removing this approach and creating a subclass of java.util.logging.Level the issue gets
resolved.
