A simple script (for a term facet) would fail often with a  
java.lang.VerifyError (but not always, even with identical input). Replaced  
it with a js script, which appears to work reliably. Anyone else ran into  
such an issue?

Couldn't even report the issue, because the mvel project appears to have  
moved to Github, but doesn't have the issue tracker enabled...
