Good question.

And I am not an expert on the topic.

But to my understanding then:
* they are relative similar in language syntax and features today
* they came from a very different (opposite) background:
   - BeanShell started as  Java interpreter and evolved
     into a full script language with optional typing
   - Groovy started as a Java-like scripting language
     without typing that added typing later
* they are used for different purposes:
   - BeanShell is very much used for JSR223 embedded
     scripting language in Java applications
   - Groovy got a much broader usage:
     . web applications (Grails framework, Groovelets)
     . more general scripting (the world dominated by
       Perl and Python)
     . JSR223 embedded scripting language in Java applications
* Groovy is more used than BeanShell - especially
   Grails have a reasonable big user base

I have only used BeanShell as embedded script engine
for 100% Java compatible. I have dabbled in Groovy for both
web and scripting.

A job search at dice.com find 239 Groovy jobs and 0
BeanShell jobs. I am sure there are plenty of jobs
where BeanShell is used but its usage is not
important enough to warrant being mentioned in the ad.
