> [PATCH] UnrestrictedFallbackResolver opens input stream for wrong resource
> --------------------------------------------------------------------------
>
> Key: XGC-131
> URL: https://issues.apache.org/jira/browse/XGC-131
> Project: XMLGraphicsCommons
> Issue Type: Bug
> Components: general
> Affects Versions: 2.7, trunk
> Reporter: Peter Schlömer
> Priority: Major
> Attachments: test-unrestricted-fallback-resolver.zip,
> xmlgraphics-commons-patch-1.txt
>
>
> There is a bug in {{UnrestrictedFallbackResolver}} (an embedded class in
> {{{}AbstractImageSessionContext{}}}) which causes it to open an input stream
> for the wrong resource (the Source) instead of the {{uri}} of the image
> passed to {{{}createSource(...){}}}.
> This happens whenever the systemId in the Source starts with {{{}file:{}}}.
> Instead of opening a {{FileInputStream}} for the image referenced by
> {{{}uri{}}}, a stream for the URI in the Source's systemId is opened.
> I discovered this because FOP is unable to include images in a PDF in one of
> our applications. Instead of reading the image file, it tries to use the FOP
> document as an image. I was able to avoid this problem on the FOP level by
> using {{{}EnvironmentalProfileFactory.createRestrictedIO(...){}}}, which
> switches to the {{RestricedFallbackResolver}} which does not have the problem.
> A patch for {{AbstractImageSessionContext.java}} is attached
> ([^xmlgraphics-commons-patch-1.txt]).
> Also attached is a Zip file countaining a Maven project
> ([^test-unrestricted-fallback-resolver.zip]). Running {{mvn test}} on this
> project will run 6 unit tests, repeating the same tests 3 times to show the
> different behaviour between
> * {{UnrestrictedFallbackResolver}} (where the test recreating the conditions
> described above fails)
> * {{RestricedFallbackResolver}}
> * a class containing the patched version of {{UnrestrictedFallbackResolver}}
