JCR-2195: Sybase 15.7 - error 'Repository data is NOT consistent', error 'expected:<588> but was:<654>'
JCR-2195: Updated the pom of the project ISPN consequently
JCR-2195: Support Sybase 15.7

Problem analysis
	* We had duplicate values in the lucene indexes because the query used to retrieve the data during the indexing process could retrieve the same nodes from one thread to another because the query doesn't support offset.

Fix description
	* As the query doesn't support offset, the idea of the fix is to be able to indicate that offset is not supported by the database and if so we synchronize the data access to prevent getting several times the same nodes and then to prevent having several nodes in the lucene indexes
