ErrorHandler takes long time at deep nested mismatched parentheses.

[miniway]

I found a case that it took long time, more than an hour, at a syntax error.

This is a simplified reproducing test case.

// TestSqlParserErrorHandling.java
@Test(timeOut = 10000)
public void testAnotherPossibleExponentialBacktracking()
{
    testStatement("SELECT id FROM t WHERE\n" +
                    "(f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "OR (f()\n" +
                    "GROUP BY id",
            "message");
}
