Session.removeAttribute is not working as expected
Posted a while back, am still struggling with the same issue. Really want to use ignite but am struggling to get this working correctly.
What I'm noticing is that session.removeAttribute doesn't really remove the
attribute, it only sets the value to null. I'm not sure if this is a setup
issue on my end or what. I thought this might be related to jsf, removed jsf and the issue persists.
Any input would be helpful, has anyone else seen this?
Thanks in advance and please help!

The closest issue that I could find to my particular issue was:
https://github.com/apache/ignite/pull/2243
I patched my local ignite repo with #2243 , redeployed to tomcat and 2
ignite nodes but am seeing the same issue.
The closest issue that I could find to my particular issue was:
https://github.com/apache/ignite/pull/2243
My setup (client/server):
- Ignite 2.5.0 (2 node cluster)
- Apache Tomcat 7
- Java 9
tomcat setenv.sh
#!/bin/sh
export JAVA_HOME=/opt/java/jdk-10.0.1
export PATH=$JAVA_HOME/bin:$PATH
export CATALINA_OPTS="--add-exports java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports java.base/sun.nio.ch=ALL-UNNAMED
--add-exports java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
--add-exports jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
--add-modules java.xml.bind"
export CATALINA_HOME=/opt/apache/apache-tomcat-7.0.86_node

Hi,
I was not able to run your project. But I created a small Maven one and
reproduced the same issue.
I changed a little bit the ticket description
https://issues.apache.org/jira/browse/IGNITE-8786 . I hope it will help
contributors to reproduce the issue and create a fix.
Best Regards,
Roman

I've updated: https://github.com/daynok/ignite-webapp
Made sure all dependencies where compiled against jdk8 (ignite, spring) and retested with
- jdk8
- tomcat 7
- ignite 2.5
Still seeing the same issue... no idea why.
In the git project I've included both ignite nodes.

Thanks for the response!
Session.removeattibute is not removing the attributes, its just setting the value to null.
Sample project: https://github.com/daynok/ignite-webapp
I've seen this behavior in both java 9 and 10.
I will try java 8 and and see if that fixes things.
Thanks again!

Hi,
1. Could you please clarify what exactly doesn't work as expected? Does
session.attributeNames() result include removed attributes?
2. JAVA_HOME=/opt/java/jdk-10.0.1 - I'm not sure that Apache Ignite was
tested on Java 10. Could you try to reproduce the issue on JDK8?
3. Could you share a reproducer - simple project on GitHub?
Best Regards,
Roman
