com.netflix.discovery.DiscoveryClient keeps using org.apache.commons.lang.exception.ExceptionUtils with commons-configuration2

[nvalencia-veradat]

Hi!
For vulnerabilities we update from commons-configuration to commons-configuration2 but com.netflix.discovery.DiscoveryClient is using a reference to org.apache.commons.lang.exception.ExceptionUtils and throws a java.lang.ClassNotFoundException.
Are there any other configuration to update commons-lang dependency?.
