Hi everyone,
I am trying to substitute the original build logger in my task with Ant 1.6.1. I have written a wrapper-class which just forwards the events to the original build logger, which works fine as long as I don't try to modify the build events. When I change a build event, however, Ant is stopping the execution with the message "BUILD FAILED
Listener attempted to access System.out - infinite loop terminated"
This is an interesting problem. Nothing you're doing sounds like a problem but somewhere something in your message handling is attempting to output a message. i.e. before one message has been delivered to the listeners something is attempting to send another. The message above gives the most common cause but it is in fact not the only possibility as I found when trying to sort out your problem.
Since your logger is loaded by an AntClassLoader it is susceptible to any logging done by that classloader. In fact I reproduced your problem and here is the stack trace
Listener attempted to access System.out - infinite loop terminated
at org.apache.tools.ant.Project.fireMessageLoggedEvent(Project.java:1991)
at org.apache.tools.ant.Project.fireMessageLogged(Project.java:2020)
at org.apache.tools.ant.Project.log(Project.java:387)
at org.apache.tools.ant.AntClassLoader.log(AntClassLoader.java:394)
at org.apache.tools.ant.AntClassLoader.loadClass(AntClassLoader.java:974)
at java.lang.ClassLoader.loadClass(ClassLoader.java:236)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:303)
at PolishLogger.messageLogged(PolishLogger.java:32)
So the deferred classloading that is triggered in your messageLogged method causes the AntClassLoader to log a message (a class being loaded).
The workaround is to trigger the class loading earlier. I changed the PolishLogger constructor as follows:
public PolishLogger(BuildLogger realLogger, Project project)
{
this.logger = realLogger;
BuildEvent event = new BuildEvent(project);
String s = new String();
StringBuffer sb = new StringBuffer();
}Note that it is not easy to ensure you have got all the classes loaded. A better solution might be to not load the PolishLogger through the AntClassLoader.
