Piotr Klimczak updated FELIX-6416:
----------------------------------
Description:
'#' 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 escaped.
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
was:
