Hi Astrid, 

     My apologies!  I made a mistake when I tried my example <all>
containing 36 children; I'm now able to reproduce your problem. 

     A fix for this bug is available by extracting the latest source from
CVS.  Sorry for any inconvenience this has caused you.

Thanks,

Henry

Hi Henry, 
  
thanks a lot for your fast response ! 
There might be a point to your suggestion with my classpath, as I am using
Jdom and Xalan too, which both use Xerces - maybe an old version. It will
take me a while to figure out a way to make all versions work together with
Xerces-J 1.4.1. If this does not solve my problem, I will send a new SOS
with my example. 
  
Thanks, 
Astrid

Hi Astrid, 

    Actually, there was a change of implementation for <all> that was first
made available in Xerces-J 1.4.0 that should have reduced the amount of
memory required for <all>.  I just tried an example in which a schema
contains an <all> with 36 children, each of which has minOccurs="0".  The
profiling tool I tried showed that the maximum amount of heap storage used
was under 4MB. 

    Could there be a problem in your CLASSPATH?  If not, please try posting
an example that reproduces your problem.

Thanks,

Henry

Hi there,

my Schema contains an <xsd:all> with about 25 elements with minOccurs="0".
Using Xerces 1.4.1 this takes more than my free 48M of memory (
java.lang.OutOfMemoryError) while using a <xsd:sequence> the same small
programm uses about 6M.
Is there hope for a change in implementation of <xsd:all> in Xerces ? Or can
anyone give me an idea of how I can avoid this OutOfMemoryError  without
fixing a special sequence for my elements ?

Looking forward to your answers,

Astrid
