MavenWrapperDownloader issue with JDK 7

[teoincontatto]

I've found this error while trying running maven wrapper (without the .jar) with an old Oracle JDK 7:

$ bash mvnw clean verify -P safer
/builds/ongresinc/scram/.mvn/wrapper/MavenWrapperDownloader.java:104: error: local variable username is accessed from within inner class; needs to be declared final
                    return new PasswordAuthentication(username, password);
                                                      ^
/builds/ongresinc/scram/.mvn/wrapper/MavenWrapperDownloader.java:104: error: local variable password is accessed from within inner class; needs to be declared final
                    return new PasswordAuthentication(username, password);
                                                                ^
2 errors
Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain

This is very easy to fix, let me know if you need me to do the PR (if finally you decide this deserve a fix).

This project is essentially frozen for development and new efforts are ongoing in the Apache Maven project itself. We therefore close this issue. Please find more information at https://github.com/takari/maven-wrapper#ongoing-migration-to-apache-maven and participate in the development there.
