Hi,
I have a CDO Server and CDO Client (using 4.2M5) that can connect to each other without problems when I use Java 6 (either 32bit or 64bit).
When I use Java 7 (which is only available in 64bit for MacOS X) for both, client and server, I get the following exception on CDO Server site, when the client tries to connect.
[ERROR] BufferUnderflowException
!ENTRY org.eclipse.net4j.tcp 4 0 java.nio.BufferUnderflowException

Any idea why this happens? I am sure that both, server and client, use the same Java version (7u13), both with 64 bit, because I print it to the console at application start.
Thanks for help!

And no problems with the 7u13 64 bit JRE and older CDO versions?

That's bad but interesting because I vaguely remember that this has come up once or twice and we've never had any chance
to reproduce this or even look at it in the context of specific environment constraints. These are some bugs that may be
related:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=299871
https://bugs.eclipse.org/bugs/show_bug.cgi?id=295989
https://bugs.eclipse.org/bugs/show_bug.cgi?id=262875
Yesterday I downloaded JDK 7u13 64 bit and I plan to run the tests with it. Not sure though when I can come to this. Can
you please submit a bugzilla to remind me?
Cheers
