Subject [jira] [Commented] (XGC-98) UndeclaredThrowableException while loading images
Date Tue, 23 May 2017 17:09:04 GMT

    [ https://issues.apache.org/jira/browse/XGC-98?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16021490#comment-16021490

mt commented on XGC-98:
-----------------------

(hit enter too soon, sorry)

https://github.com/apache/xml-graphics-commons/commit/35311e33d160513eb7f70ce4e9d505d0c0b836d5

So according to the history, the fix was made on the file AFTER it was already moved somewhere
else, and looking at the current version in the trunk, the fix is indeed not included:

https://github.com/apache/xml-graphics-commons/blob/trunk/src/main/java/org/apache/xmlgraphics/image/loader/impl/AbstractImageSessionContext.java#L121

Am I missing something here or did something go seriously wrong there and the fix is indeed
not in the trunk?

> The problem being that InvocationHandlers in the classes AbstractImageSessionContext
and ObservableStream do not handle InvocationTargetException properly, and the exception is
propagated up to the proxied interface where InvocationTargetException is not specified.
> I am not sure if you accept pull requests on Github, anyway here it is https://github.com/apache/xml-graphics-commons/pull/1
