------------------------------------
Summary: Accessing the session buffer of multiple decoders
Key: DIRMINA-1161
URL: https://issues.apache.org/jira/browse/DIRMINA-1161
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 2.1.4, 2.0.22
Environment: Ubuntu 16.04.7 LTS
Open JDK 11.0.10
Mina 2.0.22
Reporter: Pavel Garin
Fix For: 2.0.23, 2.1.5
As of Mina 2.0.17, the line of code in CumulativeProtocolDecoder
{code:java}
private final AttributeKey BUFFER = new AttributeKey(getClass(), "buffer");
{code}
has been replaced with line
{code:java}
private static final AttributeKey BUFFER = new
AttributeKey(CumulativeProtocolDecoder.class, "buffer");{code}
When using an architecture where multiple decoders inherited from
CumulativeProtocolDecoder are used, the decoders corrupt each other's data. The
key for the attribute in line
{code:java}
IoBuffer buf = (IoBuffer) session.getAttribute(BUFFER);{code}
has become the same for all decoders.
