Till Rohrmann commented on FLINK-7610:
--------------------------------------
Hi [~domenico.campagn...@gmail.com], we've recently merged FLINK-7442 which
adds a child-first classloader to Flink. With that the user code should have
preference over the system code. Thus, by including the dependency in your
fatjar (containing the user code), it should hopefully work. Could you try it
out with the latest Flink snapshot?

> Project: Flink
> Issue Type: Bug
> Components: Build System
> Affects Versions: 1.3.2
> Reporter: Domenico Campagnolo
> Priority: Blocker
> Fix For: 1.4.0, 1.3.3
>
>
> Flink job fails when I try to use the method validate((new
> StAXSource(reader))) from the class _javax.xml.validation.Validator_ because
> StAXSource is [supported since xerces
> 2.10|https://stackoverflow.com/questions/20493359/staxsource-not-accepted-by-validator-in-jboss-eap-6-1]
> and the library _flink-shaded-hadoop2-uber-1.3.2_ contains the 2.9.1 version
> in it.
> I also included the dependency to the latest version of xerces 2.11.0 into my
> job-jar but it still does not work.
> I also added that library into _%FLINK_HOME%/lib/_ folder hoping it would be
> loaded on the classpath at the boot, overriding the original one, but it does
> not work either.
> See the cause:
> _Caused by: java.lang.IllegalArgumentException: *Source parameter of type
> 'javax.xml.transform.stax.StAXSource' is not accepted by this validator*._
