Hi Armin,
Yes I just tested it with the 1.0.3 cvs branch and it is reproducable.
Strewth!
Do you want me to enter an issue in jira with an attached example (maybe
my setup is wrong?)?
yes please. I will try to setup an test case for this issue.
Regards,

Hi Martin,
I assume it's a 1.x specific issue. I didn't do the backport of 1.0.x
branch to 1.x yet (it's really much work and I didn't find the time to
do it). Is it reproduceable with the 1.0.x branch or 1.0.3?
regards,
Armin

Hi,
I noticed that ojb gets into an infinite loop when there are circular
dependencies between objects and refresh(=true) is specified on the
reference descriptors.
My testcase has a class A which points to B and vice versa and there
is an instance of A (A1) which points to an instance of B (B1) and B1
points back to A1.
When A1 is read and a getB is done the system gets in an infinite loop.
Looking at the stacktrace I see that the following is happening:
When A1 reads B1 then the relations of B1 are refreshed which again
gets A1 from the cache which reads B1 and B1 refreshes its references
which gets A1 from the cache which again refreshes it references etc.
See also the repository.xml below.
Is this really an issue or is my setup wrong?
I am looking at the latest 1.1 cvs version and using the PB api.
Here is my repository.xml:
