[jira] [Commented] (FLINK-7610) xerces lib conflict
[ https://issues.apache.org/jira/browse/FLINK-7610?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16208996#comment-16208996 ]
Till Rohrmann commented on FLINK-7610:
--------------------------------------
Hi [~domenico.campagnolo@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?

> 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*._
