Like you said, in the normal case, the property name starts with a lower case character, e.g. "foo" corresponds to "getFoo()". But if the getter method name has more than one capital character after "get" (e.g. "getQSeqNumber()" in your case), the case is preserved in the property name. Hence, in your case the property name is "QSeqNumber". If you want the property name to be "qseqNumber" rename the getter method to "getQseqNumber()".
