/**
* The algorithm of OpenEJB deployments class-path inclusion and exclusion is implemented as follows:
* 1- If the string value of the resource URL matches the include class-path pattern
* Then load this resource
* 2- If the string value of the resource URL matches the exclude class-path pattern
* Then ignore this resource
* 3- If the include and exclude class-path patterns are not defined
* Then load this resource
*
* The previous steps are based on the following points:
* 1- Include class-path pattern has the highest priority
* This helps in case both patterns are defined using the same values.
* This appears in step 1 and 2 of the above algorithm.
* 2- Loading the resource is the default behaviour in case of not defining a value for any class-path pattern
* This appears in step 3 of the above algorithm.
