Test case: class Test { Object m(boolean cond1, boolean cond2) { Object o; if (cond1) { if (cond2) { o = null; } else { o = null; return null; } } return null; } } Thanks to the original bug reporter and his team for their commitment. Also, thanks for their help to find a test case that reproduces this bug.
