session.removeAttribute is not removing the attribute

[dshaw <ds...@medata.com>]

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.  This behavior is causing issues with out existing
code. 

Any input would be helpful.

Thanks in advance!

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.

My setup:

Using ignite 2.5 with tomcat 7 (jdk 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

client-config.xml (used by tomcat 7)
