             Fix For: 3.1.0-GA


The resource resolver resolve() method sometimes fails but does not provide information that helps to understand the cause of the error:
- fails with an NPE if the provided path is null on the line "return context.getResource(path.substring(i1));" which is hard to distinguish whether the context or the path variable is null
- does not respect the contract: if the context is null then null must be returned "Returns a {@link org.exoplatform.portal.resource.Resource} for the provided path or null if the resource cannot be resolved".
