Unfortunately cross-check is not wrapped by the Java-api. However you can easily code it yourself, see http://answers.opencv.org/question/15/how-to-get-good-matches-from-the-orb-feature. There is also suggested the ratio-test as another way of pruning the points.

False-positives matches should be either rejected beforehand or during findHomography (which you actually also do by applying RANSAC/LMEDS). More suggestions can also be found in this answer: http://answers.opencv.org/question/12898/how-to-know-if-findhomography-warpperspective-will/
