Review Comment:
> jar:foo:file is actually prohibited by new URL(), why not allow this
impossible scenario?
Prohibited by who? Thing is that we actually only support `jar` and `file`,
now you allow `jar:(whatever:)*file` - this is allowed by `URL` and
`URLHandler` API. Don't think it is what we want so we should just unwrap once
or let the caller unwrap it more before passing the path to the archive IMHO.
Nested jar support is done through other `Archive` implementation like
https://github.com/Talend/component-runtime/blob/master/component-runtime-manager/src/main/java/org/talend/sdk/component/runtime/manager/xbean/NestedJarArchive.java
but it requires some knowledge about the enclosing structure so better to not
try to be too clever there IMHO.
