#1509 [java] InvalidSlf4jMessageFormat: NPE

[Geniy00]

I have problem with InvalidSlf4jMessageFormat.
My env:
PMD 5.5.1
gradle 2.14.1

package my.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Test {

    private static final Logger log = LoggerFactory.getLogger(Test.class);

    public static void main(String[] args) {
        log.info("1" + "2");
    }
}

It throws NPE with gradle related stacktrace (see attached file):

:pmdMain
Exception applying rule InvalidSlf4jMessageFormat on file E:\srcOther\test\src\main\java\my\test\Test.java, continuing with next rule
java.lang.NullPointerException

You can see full project in attached files.
run:
gradle clean pmdMain

I can't reproduce this bug with pmd client lib without gradle.

This bug will be fixed with PMD 5.5.2.
