groovy regex with adjacent matches

How can I get the count of all instances of a regex?

This gives the expected result:

groovy> 'banana'.findAll(~/\wa/).size() 
Result: 3

but this gives the same: 

groovy> 'banaana'.findAll(~/\wa/).size() 
Result: 3

How can I find all 'a's preceded by a letter, including another 'a'?

TIA

Brian

I think using lookbehind will give you the right output. Because lookarounds are zero length assertions. They do not consume characters in the string, but only assert whether a match is possible or not.
