Serge Baranov commented on DIRMINA-663:
---------------------------------------

Done more testing:

CentOS 5.2 - works fine with M4/RC1
Windows 2003 Server x64 -- works fine with M4/RC1
Windows Vista 32-bit laptop -- works fine with M4/RC1
Windows VIsta 64-bit clean VMWare image -- works fine with M4/RC1
Windows VIsta 64-bit real system -- fails with M4/RC1, works fine with M3 
(under any JVM)

So, it looks like the problem is specific to both the windows 
environment/hardware and the MINA version. Really puzzled. Any ideas?

>             Project: MINA
>          Issue Type: Bug
>          Components: Filter
>    Affects Versions: 2.0.0-RC1
>         Environment: JDK 1.6.0_12 32-bit, Windows Vista 64-bit, MINA 
> 2.0.0-RC1 (up to current date trunk).

> To reproduce get the mina_test_2.0.zip from DIRMINA-609.
> It seems to be working even worse with the current trunk version, it takes ~5 
> seconds between messages and then times out after the first message, if wait 
> is increased to 10 seconds, it times out after the second message:
> time       = 03:49:36.320
> remaining  = 1024
> limit      = 1024
> capacity   = 2048
> time       = 03:49:41.619
> remaining  = 2048
> limit      = 2048
> capacity   = 2097156
> java.lang.AssertionError: No message received
> The issue differs from DIRMINA-609 as it affects not only large messages, but 
> any message that doesn't fit into buffer (when doDecode returns false) and 
> also all the subsequent messages (when doDecode returns true).
> It's a serious issue making CumulativeProtocolDecoder completely useless.
