Section 11.1.1 "Construction by Properties", page 103, paragraph 6, bullet point 2 says 'the Properties instance passed to the static method will contain a property with a key of "javax.jdo.spi.PropertiesResourceName", and a value equal to the name of the resource'. The string constant in the JDO API code doesn't exist. javax.jdo.Constants contains the following member:
static String PROPERTY_SPI_RESOURCE_NAME
I suggest updating the spec to reflect the correct string in the code rather than modifying the code. I discovered this in JDO 3.1, but may effect versions of the specification beginning with 2.1 and later as the javadoc for this constant includes "@since 2.1".
