JVM error when using jfconfig with Dropwizard 1.3.0+

[andreweacott]

Using jfconfg 4.1.12 with a Dropwizard 1.3.0+ application causes a JVM error when the JFConfig class is loaded :

java.lang.VerifyError: Bad type on operand stack
      Exception Details:
        Location:
          com/energizedwork/justConf/JFConfig.envVarSubstitution(Lio/dropwizard/configuration/ConfigurationSourceProvider;)Lio/dropwizard/configuration/ConfigurationSourceProvider; @13: invokespecial
        Reason:
          Type 'io/dropwizard/configuration/EnvironmentVariableSubstitutor' (current frame, stack[3]) is not assignable to 'org/apache/commons/lang3/text/StrSubstitutor'
        Current Frame:

Appears to be a class incompatibility with jfconfig build dependencies.
i.e. Rebuilding jfconfig using the 1.3.0 dropwizard BOM instead of 1.1.4 produces an artifact that doesn't cause this issue.
