Description

The hbase-shaded-client artifact was introduced in HBASE-13517. Thank you very much for this, as I am new to Java building and was having a very slow-moving time resolving conflicts. However, the shaded client artifact seems to be missing javax.xml.transform.TransformerException. I examined the JAR, which does not have this package/class.

Steps to reproduce:

Java:

package com.mycompany.app;
