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.
