Description

Code was introduced in version 3.6.0 which assumes that all JAR file URIs are composed of two parts - the path to the JAR file, and the path to the resource within the JAR file, separated by a an exclamation mark.

This means that deployments using "uber" jars now fail if the schema is located inside a JAR inside BOOT-INF/lib within the top level JAR.

A microservice deployment with a schema URI such as this fails:

jar:file:/home/serviceuser/service.jar!/BOOT-INF/lib/some-other-jar.jar!/some-schema.dfdl.xsd

The code at https://github.com/apache/daffodil/blob/main/daffodil-lib/src/main/scala/org/apache/daffodil/lib/util/Misc.scala#L185 then fails on the assertion that there are 2 parts after it splits by the separator.

Versions up to 3.5.0 work fine.
