Previously, the spring bash script added . to the classpath but the
Windows spring.bat script did not. This commit aligns the classpath
of the two scripts by removing . from the classpath in the bash
script.

Update `StaticResourceJars` to catch both `IOException` and
`InvalidPathException` when checking URLs. Prior to this commit only
`IOException` was caught which worked on Java 8 but not Java 11 or
above.

Update `ConfigFileApplicationListener` to throw a better exception if
`classpath*:` is used as a location.
