Sebastien Deleuze 7ea69fb96c Improve ResolvableType.hashCode() for better performance Prior to this commit, when there was a lot of entries in the ResolvableType.cache HashMap, getting a simple value could take a lot of time due to a lot of calls to ResolvableType.equals(). ResolvableType.equals() used this.type, getSource(), this.variableResolver.getSource() and this.componentType, but ResolvableType.hashCode() used only this.type. With this commit, ResolvableType.hashCode() now uses the same fields than ResolvableType.equals().

Sebastien Deleuze 7ea69fb96c Improve ResolvableType.hashCode() for better performance

Prior to this commit, when there was a lot of entries in the
ResolvableType.cache HashMap, getting a simple value could
take a lot of time due to a lot of calls to ResolvableType.equals().
ResolvableType.equals() used this.type, getSource(),
this.variableResolver.getSource() and this.componentType, but
ResolvableType.hashCode() used only this.type.

With this commit, ResolvableType.hashCode() now uses the same
fields than ResolvableType.equals().
