> 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();
> e2.addSuppressed(e1);
> e1.addSuppressed(e2);
> LoggerFactory.getLogger("root").error("Error", e1);
> {code}
> Will throw the following:
> {code:java}
> Exception in thread "main" java.lang.StackOverflowError
> 	at java.util.HashMap.hash(HashMap.java:338)
> 	at java.util.HashMap.get(HashMap.java:556)
> 	at java.lang.ClassLoader.getPackage(ClassLoader.java:1608)
> 	at java.lang.Package.getPackage(Package.java:334)
> 	at java.lang.Class.getPackage(Class.java:783)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.toCacheEntry(ThrowableProxy.java:495)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.toExtendedStackTrace(ThrowableProxy.java:547)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.<init>(ThrowableProxy.java:113)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.toSuppressedProxies(ThrowableProxy.java:588)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.<init>(ThrowableProxy.java:116)
> 	at org.apache.logging.log4j.core.impl.ThrowableProxy.toSuppressedProxies(ThrowableProxy.java:588)
> {code}
> A simple stack trace printout will produce the following:
> {code:java}
> java.lang.Exception
> 	at NewClass.main(NewClass.java:95)
> 	Suppressed: java.lang.Exception
> 		at NewClass.main(NewClass.java:96)
> 	[CIRCULAR REFERENCE:java.lang.Exception]
> {code}
