NullpointerException if reference name in composite file needs to match exactly what is defined in java file

Reference name in composite file needs to match exactly what is defined in java file : example : in java reference :

@Reference
public void setPricechgLoggingWSService (PricechgLoggingWSService pricechgLoggingWSService)

{ this.pricechgLoggingWSService = pricechgLoggingWSService; }

in composite file : <reference name="pricechgLoggingWSService">

If the mismatch occurred, NPE will be generated when composite starts

I'm not sure if the stack trace would be the same, but besides the error where you have a typing mismatch you get the same net result if your @Reference is not placed on a method/field with public or protected access (i.e. if you use a private or pkg (dflt) modifier). Might as well tackle @Property at the same time.. probably the same state of affairs there.
