[JAVA] TEST CASE 67

[luca-digrazia]

Fix the Java test case 67:

public void test67() throws Exception {
        String query = "if (EXPR<0>) { --> if (EXPR<0> && EXPR) {";
        String candidate = "if (contentType == null) { --> if (contentType == null && charset == null) {";
        assertTrue(App.runJunit(query, candidate));
    }
