After Berliner's agreement, go to French island (4)

I believe the answer is:

java

I'm a little stuck... Click here to teach me more about this clue!

'island' is the definition.
(I know that Java is a island)

I can't explain the remainder of the clue.

(Other definitions for java that I've seen before include "Catlike" , "Jakarta's island" , "Most populous Indonesian island" , "Indonesian island - computer programming language" , "Coffee - computer programming language" .)

I've seen this clue in The Times.
