Neil Robertson-Ravo shared an interesting bug with me:
<cftry><cfcatch></cfcatch></cftry>
When run, this generates a error:
(class: cftest2ecfm370320109, method: runPage signature: ()Ljava/lang/Object;) Illegal exception table range
What makes this template interesting is that as soon as you add a line break after the first cftry, it goes away. Neil has entered a bug report for it.
