Seam Catch exception stack trace filter API

FooMethodStackTraceFilter.java

public class FooMethodStackTraceFilter implements StackTraceFilter<StackTraceElement> {
   public boolean discard(StackTraceElement element) {
      return element.getMethodName().equals("foo");
   }
}

JBossEjbStackTraceFilter.java

public class MyStackTraceFilter implements StackTraceFilter<Class> {
   public boolean discard(Class element) {
      return element.getName().startsWith("org.jboss.ejb");
   }
}

StackTraceFilter.java

public interface StackTraceFilter<T> {
   boolean discard(T element);
}

Okay, looking good. Now, what if I have a com.jboss.seam.Bar#foo() in there, added or not?

A value of false wins?

Now a value of false discards.
