Domenico Campagnolo created FLINK-7610:
------------------------------------------

             Summary: xerces lib conflict
                 Key: FLINK-7610
                 URL: https://issues.apache.org/jira/browse/FLINK-7610
             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 on 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.
