OObjectDatabaseTx.browseClass: Returns wrong records with multiple classes per cluster

[dxxr]

OrientDB v 1.5.1

With multiple classes created in one cluster, browseClass(...) returns wrong records.
It seems to always include the first record of the first class created, even if other classes are browsed. (Select from class seems ok)

Example using the console (assuming the default cluster has ID 3):
create class ClassA cluster 3;
create property ClassA.name String;
create class ClassB cluster 3;
create property ClassB.name string;
insert into ClassA (name) values ('Class A - 1');
insert into ClassA (name) values ('Class A - 2');
into ClassB (name) values ('Class B - 1');
insert into ClassB (name) values ('Class B - 2');
browse class ClassA;
