            Description

            The bug is related to a support case where some page content was not being displayed. After closer inspection the problem appeared to be regression introduced in 6.1.3. After quite a bit of debuging the regression was located and was do to the double entry into getting two object from the same compressed entry. When the font classes encoding property is retrieved it offset the object pointer and subsequent lookups return the wrong object.

            Further investigation is needed to figure out why this error is occurring.

              I've had a chance to revisit this issue with regards to getting more then one object at a time from an object stream. I've added a restore cursor which seems to be a better solution and will pick up other potential issue. I've also move the stream lock out a bit so the sub object values are less likely to be affected by multiple thread access.

              an object looking up an other object in the same stream.
