Hi,
I have made new tests of Jeremie to see if I could reproduce the memory leak, but I couldn't.
The test is simple :
// simplified client code
Tester tester = (Tester) Naming.lookup("initial-server-name");
while (true) {
String new_name = tester.newName();
tester = (Tester) Naming.lookup("initial-server-name");
}
// simplified server code
class TesterImpl implements Tester {
static int id = 0;
String newName() {
String oldname = "tester"
+ i;
Naming.unbind(oldname);
i++;
String new_name = "tester"
+ i;
Naming.rebind(new_name,
this);
return new_name;
}
}
The client thus repeatedly invokes the server that calls the registry to add and remove objects. This test has been running all night without any problem. I have also tested a slightly different scenario in which a new TesterImpl object is put in the registry during each iteration, the old one being unexported (this scenario requires methods I have just added to Jeremie). It works equally well.
This shows that the problem is not with the registry implementation, nor with a memory leak during Jeremie invocations. I can think of two other possibilities:
- the problematic examples require distributed garbage collection, provided by RMI but not by Jeremie (and not by RMI/IIOP);
- there is a memory leak in the transaction context transmission (not tested by the above example).
Best regards,
Bruno

I was so involved in the release process of the version that
I have not tried to reproduce the "memory leakage problems with Jeremie"
If somebody can easily reproduce it and tell us if the new version
of jonathan fix the bug it will be fine!
