Getting java.lang.ExceptionInInitializer Error with POM model

Description

Getting issues while initializing page factory. Same code worked perfectly with Selenium version 2.53.0 and java-client 3.3.0. When I upgraded selenium to 3.141 and java-client to 7.0.0 I started getting this error.
I am using Cucumber based POM Framework with for Maven & Appium as build test tools. Have referred issues related to Page Factory for Appium but none of it helped.

Can anyone please suggest what am I missing here? Thanks for help!

Environment

• Appium server version or git revision if you use some shapshot:
• Desktop OS/version used to run Appium if necessary:
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe:
• Mobile platform/version under test:
• Real device or emulator/simulator:

If you are reporting a bug, always include Appium logs as linked gists! It helps to define the problem correctly and clearly.

Start with the linked gist containing the reproduction and exception stack trace, then compare the reported Selenium and java-client versions. Fill in the missing environment details and verify the failure with the provided Maven, Cucumber, POM, and Appium setup; done requires a confirmed cause and a reproducible resolution.
