> If an exception with a circular-referenced exception (suppressed, or otherwise) is logged,
log4j will throw a StackOverflowError:
> {code:java}
>         Exception e1 = new Exception();
>         Exception e2 = new Exception(e1);
>         e1.initCause(e2);
>         LogManager.getLogger().error("Error", e1);
> {code}
> Will throw the following:
> {code:java}
> java.lang.StackOverflowError
> 	at java.util.Vector.elementData(Vector.java:730)
> 	at java.util.Vector.elementAt(Vector.java:473)
