Here is a question and an answer from a list of questions on Cuba:
Q. What is a "java" bag?
A. "Java" is the Cuban word for bag. Because of the shortage and high cost of personal hygiene articles, the State provides all employees in the public service sector with a free bag of toiletries every month. This bag usually contains deodorant, toothpaste, shampoo, razors, etc.
My questions here are the following: Does this expression exist in American English (perhaps as an idiom)? If yes, how and when is it used?
