Description

I've created a simple log4j project: [log4j-test.zip](https://github.com/github/codeql/files/7886955/log4j-test.zip)

It uses log4j 2.11 which is vulnerable to JNDI injection, and I've verified the vulnerability exists. Now I need to verify codeql also works. So I created the java database with:

```
codeql database create java-database -l=java -c="mvn clean install -file pom.xml" --overwrite
```

Then I opened the starter project and uses `ql/java/ql/src/Security/CWE/CWE-074/JndiInjection.ql` to test it, but no results came out.
