[jira] [Commented] (BEAM-6657) java.lang.ArrayIndexOutOfBoundsException

    [ https://issues.apache.org/jira/browse/BEAM-6657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16938301#comment-16938301 ] 

Vishwas commented on BEAM-6657:
-------------------------------

This is not a bug. The new rowSchema needs to be set when creating the pipeline, in this case old schema is used. I have attached the modified java code for the example [^TestTextIo.java]

With this change the code works without any issue.
