> FELIX-6326 breaks JDK9+ URLClassLoader by allowing incorrect URL paths
> ----------------------------------------------------------------------
>
> Key: FELIX-6416
> URL: https://issues.apache.org/jira/browse/FELIX-6416
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-6.0.4
> Environment: MacOS
> Reporter: Piotr Klimczak
> Assignee: Jean-Baptiste Onofré
> Priority: Blocker
>
> '#' sign represents URL fragment and is not valid URL path element.
> As per spec it is not allowed for it to be a part of path and instead must be
> URL encoded.
> So for example for file in location in UNIX systems:
> "/Users/piotrklimczak/test#", the valid URL encoding to load it in Java is:
> {code:java}
> new File(new URL("file:///Users/piotrklimczak/test%23").toURI()) {code}
> Works.
> While
> {code:java}
> new File(new URL("file:///Users/piotrklimczak/test#").toURI()) {code}
> Returns java.lang.IllegalArgumentException in Java: URI has a fragment
> component
> FELIX-6326 effectively allows '#' to be accepted as valid URL path element,
> which in turn breaks JDK9+ URLClassLoader which is using URL fragment (ref)
> to deal with multi-release jars.
> This then breaks pax-transx-tm-narayana installation in Karaf 4.3.1 (which
> uses URLClassLoader).
> In my opinion FELIX-6326 should be reverted and users should be encoding
> special characters correctly in their resource paths as per above example.
> I've taken a risk to mark it as a blocker as effectively it blocks using
> Narayana TM, rendering Karaf 4.3.1 not usable for us.
> Feel free to downgrade it if my judgement failed here.
