> The problem is in the following method of the GroovyLanguage
> @SuppressWarnings("unchecked")
> protected Class<Script> parseExpression(String expression) {
> return new GroovyClassLoader().parseClass(expression);
> }
> It uses the default constructor to create GroovyClassLoader, which uses Thread context classloader, which may not be equal to the classloader of the bundle where the camel context is defined.
