Michael Bouschen commented on JDO-162:
--------------------------------------

Some comments about the patch

CharacterAndStringLiterals.java:
- I propose to change the filter of the invalid query to "charNotNull == 'O.'". 
- I propose to add a new invalid query  using double quotes: "charNotNull == \"O.\""
- OR is not a valid operaor in JDOQL.
- I propose to add another valid query using double quotes:  stringNull.startsWith(\"Even\") OR charNotNull == \"O\"

PositiveRange, RangeAsString:
- I propose to add another test query with a non zero from range.

IdentifiersEqualFieldNames:
- I think we need two test queries here:  one accesing a persistent field such as "this.firstname = 'emp1First'" and another one uinsg a constatnt such as "this.personid < Byte.MAX_VALUE.

> We need 5 new test classes, one for each of the following assertions: 
> - A14.6.2-42: There is no distinction made between character literals and String literals. Single character String literals can be used wherever character literals are permitted. String literals are allowed to be delimited by single quote marks or double quote marks. This allows String literal filters to use single quote marks instead of escaped double quote marks.
> - A14.6.2-43: Identifiers that are persistent field names or public final static field names are required to be supported by JDO implementations.
> - A14.6.8-1: setRange(long fromIncl, long toExcl).
> - A14.6.8-2: If ((toExcl - fromIncl) <= 0) evaluates to true, if the result of the query execution is a List, the returned List contains no instances, and an Iterator obtained from the List returns false to hasNext(). If the result of the query execution is a single instance (setUnique(true)), it will have a value of null.
> - A14.6.8-3: setRange(String range).
> Details can be found on Wiki page http://wiki.apache.org/jdo/QueryTests#OtherLanguageChanges.
