Parsing fails with PatternSyntaxException on invalid pattern (when example is present)

[constint]

Tested with parser version 1.0.11 For the given raml file

#%RAML 1.0
title: "Invalid pattern"
version: "1.0.0"
protocols:
- "HTTP"
types:
  stringType:
    type: string
    pattern: "\\X"
    example: "abc"

Then parser fails with the following stacktrace (instead of providing a RamlValidationResult)
