ISSUE 864 Fix primitive id field RSQL filter

[hellohanchen]

In #814, INFIX, POSTFIX and PREFIX RSQL filters are supported for Number.class. But for primitive classes, the check Number.class.isAssignableFrom(relationshipType) would not work.

Possible Solution

Number.class.isAssignableFrom(relationshipType) || relationshipType == long.class || relationshipType == int.class

Steps to Reproduce (for bugs)

Create a class with id field type long and run a filter id=="*1*" on that would return InvalidValueException: Invalid value: *1*
