Bug ID: 66409
Summary: Loading Resources with Blanks in Path Fails
Product: Tomcat 9
Version: 9.0.70
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: michael-christoph.ratzenbo...@cgm.com
Target Milestone: -----
Since Tomcat 9.0.70, the following problem occurs.
When loading resources (e.g. a font from a jar file) an URISyntaxException is
thrown, if the URI is not valid. However, this also includes URLs which contain
blanks, meaning that loading resources that contain a blank, the resource
cannot be loaded since the determined URL is null.
E.g. Tomcat 7.0.69 was able to load the following resource: "MS Sans
Serif.ttf", whereas Tomcat 7.0.70 is not able to load it anymore, with the
following debug message:
04-Jan-2023 09:56:22.921 FEIN [http-nio-7000-exec-12]
org.apache.catalina.webresources.AbstractArchiveResource.getURL Unable to
determine a URL for the resource

Sans Serif.ttf]
java.net.URISyntaxException: Illegal character in opaque part at index

Some investigation on our side showed that
org.apache.cataline.webresources.AbstractArchiveResource#getURL() has changed
from version 7.0.69 to 7.0.70. Instead of using the java.net.URL directly,
java.net.URI(url).toURL() is used now. The problem is, that the URL is not
encoded properly.
The hardware and OS should not influence this bug.
