I just found out through a thread dump that db4o 7.4 seems to be instantiating an object that i was persisting.
This is a very major bug cause that the call to the object's constructor leads to a whole chain of calls which eventually deadlocks my program.
In any case, db4o should not call the constructor cause that may in turn call other methods ...

I used db4o client/server features and added objects at the server end and committed them. When I try to get those objects in a client program using Native Queries the IList<> always returns 0 objects. Using Query by example I get the desired result.I know my query is right because I tested it on the server program and it works but somehow ...

I'm having a problem storing and retrieving an object that contains a HashSet wrapped in a SynchronizedSet, e.g.:
class MyClass {
private Set<UniqueID> ids = Collections.synchronizedSet(new HashSet<UniqueID>());
...
}
I can store this object and retrieve it and it will contain the UniqueIDs that I added to the ...

String s;

new File(''test.yap'').delete();

private static final long serialVersionUID = 1L;
private String name;
private List<SimplePersonIf> friends;

hi every one,
Thanks In advance,
I had array fields duplicated when querying Objects with array field type in Object manager 6.1.401. I use db4o version 6.1.501 which handles the Objects of same type well.
I was having the stored fields of the class duplicated every time i reopen the data base file in this ...

Hello,
I still got problems to get all the elements of Db4o aware collections deleted. I attached a very simple Test case. Hope this bug can be fixed.
//File ListTest.javaimport com.db4o.Db4o;import com.db4o.ext.ExtObjectContainer;import junit.framework.TestCase;import java.io.File;import java.util.ArrayList;import java.util.Date;import ...

Thanks Patrick, with the SVN version the test runs perfectly.
However, if I open the database with OM then those primitive array stored fields will be duplicated but with their wrappers as type.
The print of the test case will be:
Stored Class: ArrayTest$MyClass * primitiveBooleanArray <[GenericClass ...
