CWE: CWE-89 \u2014 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component.

Code:
    public void testLikeToSQL() {
        Assert.assertEquals(
                "BroadWay%", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "BroadWay*"));
        Assert.assertEquals(
                "broad#ay", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broad#ay"));
        Assert.assertEquals(
                "broadway", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broadway"));

        Assert.assertEquals(
                "broad_ay", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broad.ay"));
        Assert.assertEquals(
                "broad.ay", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broad!.ay"));

        Assert.assertEquals(
                "broa''dway", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broa'dway"));
        Assert.assertEquals(
                "broa''''dway",
                LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broa" + "''dway"));

        Assert.assertEquals(
                "broadway_", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broadway."));
        Assert.assertEquals(
                "broadway", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broadway!"));
        Assert.assertEquals(
                "broadway!", LikeFilterImpl.convertToSQL92('!', '*', '.', true, "broadway!!"));
    }
