I tried a rule like: $err => note("Found") :: $err instanceof org.openide.ErrorManager and I got "ErrorManagerLog:4: invalid rule format: "$err" is missing a => expression (perhaps missing braces around a multi-statement block?)" a bit scary message given the fact that I am missing ";". So I tried $err => note("Found") :: $err instanceof org.openide.ErrorManager; but I got: org.netbeans.jackpot.engine.EngineException: Error executing operator at

There are three problems here: . rules that don't end with semi-colons need to be reported better; . the rule language should be able to accept expressions (no semi-colon) and not just statements; and . the javac assertion error needs to be addressed. The first two problems are now issues 73825 and 73826. I'll investigate this third issue ASAP.
Fixed misleading error message.
Probably fixed at least I was able to execute: /** get rid of error manager notify (1) */ $err.notify($t) => org.openide.ErrorManager.getDefault().notify($t) :: $t instanceof java.lang.Throwable && $err instanceof org.openide.ErrorManager;
