Closes gh-26743

Update `JarFile` and `JarFileWrapper` classes so that they no longer
close the `JarFile` early if a `SecurityManager` is in use.

Prior to this commit, the closed `JarFile` would cause (an ultimately
swallowed) NPE in `ZipFile` which manifested itself as a
`ClassNotFoundException` when starting the app.

This commit aligns int and long so that a random number is generated
by delegating to ints/longs in the JDK's Random API. In the case of a
single bound value, it needs to be greater than 0 because 0 is used as
the lower bound.

Previously, LoggingSystem#get would chose Logback by the sole presence
of a class in logback-core, with the assumption that logback-classic is
also on the classpath. An app that only had the former would therefore
fail.

This commit updates the condition to check for a class in
logback-classic instead.

Update `ImageName` and `ImageReference` to use distinct regex patterns
to parse specific parts of the value. Prior to this commit a single
regex pattern was used which could hang given certain input strings.

If the property is explicitly configured, that gets used.
If none are present, we rely on Spring Security's default value of
REDIRECT.
