Modeshape 4.0+ no longer supports PATH set queries

Should a repository contains the following nodes:

/myvdb1 [vdb:virtualDatabase]
/myvdb2 [vdb:virtualDatabase]
/myvdb3 [vdb:virtualDatabase]

In Modeshape 3.8, I can do the following query and find 3 results:

SELECT * FROM [nt:base] WHERE PATH() IN ('/myvdb1', '/myvbd2', 'myvdb3')

In Modeshape 4.1, this query returns 0 results.

If I run the following query, I can get back 3 results (1 for each query) as expected:

SELECT * FROM [nt:base] WHERE PATH() = '/myvdb1'
SELECT * FROM [nt:base] WHERE PATH() = '/myvdb2'
SELECT * FROM [nt:base] WHERE PATH() = '/myvdb3'

Therefore, it seems the IN keyword no longer works with the PATH function if the values are simple strings. I note that there are no explicit tests for this in the modeshape codebase.

Additionally, queries like the following that use PATH/IN with a subquery do return the correct result.

SELECT * FROM [nt:base] WHERE PATH() IN (
    SELECT * FROM [vdb:virtualDatabase]
)
