Local fix

• Instead of usingthrow new ExceptionInInitializerError("Exception
  message here");You can use the below snippets of code to get
  required exception.Throwable exception = new
  Throwable("Exception message here");throw new
  ExceptionInInitializerError(exception);
  

Problem summary

• The problem is caused when a user created
  ExceptionInInitializerError without an initialized cause is
  thrown inside a static initializer.

  ExceptionInInitializerError instead of NullPointerException
