"Weird" Error Messages

Whilst trying to use the nifty management console included with JRockit (supposedly the world’s fastest JVM), I recieved this error

COM.jrockit.common.util.AssertionFailedException: Received a weird y = 114 or weird time = 1041533639613 class = com.jrockit.console.ui.chart.DataSourceMemoryHeap

That’s the first time I’ve ever been told by a machine that something was “weird.”
