Matteo Franci commented on FOP-3109:
------------------------------------
After further investigation, it appears the different behaviour was introduced
at line 311 of
[FopFactoryBuilder|[http://example.com](https://github.com/apache/xmlgraphics-fop/blob/fop-2_8/fop-core/src/main/java/org/apache/fop/apps/FopFactoryBuilder.java)|http://example.com]%28https//github.com/apache/xmlgraphics-fop/blob/fop-2_8/fop-core/src/main/java/org/apache/fop/apps/FopFactoryBuilder.java)]
:
{code:java}
protected FopFactoryBuilder setConfiguration(Configuration cfg, boolean
parse) {
fopFactoryConfigBuilder.setConfiguration(cfg);
if (parse) {
try {
new FopConfParser(cfg, this);
} catch (SAXException e) {
throw new RuntimeException(e);
}
}
return this;
}
{code}
The construction of the
[FopConfParser]([https://github.com/apache/xmlgraphics-fop/blob/trunk/fop-core/src/main/java/org/apache/fop/apps/FopConfParser.java)]
at line 164 invoke the configure with a new default ResourceResolver instead of
the custom set in FopFactoryBuilder
{code:java}
public FopConfParser(Configuration cfg, FopFactoryBuilder
fopFactoryBuilder) throws SAXException {
this.fopFactoryBuilder = fopFactoryBuilder;
configure(fopFactoryBuilder.getBaseURI(),
ResourceResolverFactory.createDefaultResourceResolver(), cfg);
} {code}
And at line to 294 override the ResourseResolver for the FontManager with the
default one :
{code:java}
// configure font manager
new FontManagerConfigurator(cfg, baseURI,
fopFactoryBuilder.getBaseURI(), resourceResolver)
.configure(fopFactoryBuilder.getFontManager(), strict); {code}
(All line number reference are for version 2.8 of Apache FOP).
A possible work around has been committed on the POC repository :

> Custom ResourceResolver seems to be ignored in version 2.7+

> Key: FOP-3109
> URL: https://issues.apache.org/jira/browse/FOP-3109
> Project: FOP
> Issue Type: Bug
> Components: renderer/pdf, unqualified
> Affects Versions: 2.7, 2.8
> Environment: Tested on :
> JDK 1.8.0_333 and JDK 11.0.16
> Apache Maven 3.8.6
> Windows 10 and Ubuntu 22.04
> Reporter: Matteo Franci
> Priority: Major
>
> It's the first time I open an issue on Apache JIRA. I read the guidelines but
> I hope I did not make mistakes.
> When creating a FopFactory with a custom ResourceResolver, the resolver seems
> to be ignored in Apache FOP 2.7 e 2.8.
> The same code apperead to work properly in Apache FOP 2.6.
> {code:java}
> ResourceResolver resolver = new ClassLoaderResourceResolver();
> FopFactoryBuilder builder = new FopFactoryBuilder(new
> File(".").toURI(), resolver );
> builder = builder.setConfiguration(new
> DefaultConfigurationBuilder().build(fopConfigStream));
> FopFactory fopFactory = builder.build(); {code}
>
> Here is a proof of concept with a custom ResourceResolver loading font from
> the class loader when the path starts with classpath://
