<p><font face="Arial">Hi,</font></p>
<p><font face="Arial">a few days ago I created the Jira issue
KEYCLOAK-3311.</font></p>
<p><font face="Arial">Its about the following exception when "k_logout"
request from the keycloak server is coming in:</font></p>
<p><font face="Arial">IllegalStateException: UT000126: Attempted to
do blocking IO from the IO thread. This is prohibited as it may
result in deadlocks<br>
</font></p>
<p><font face="Arial">Has anybody experienced the same? Is there a
workaround?<br>
</font></p>
<p><font face="Arial">Currently this error prevents the logout from
the secure proxy and therefore the protected<br>
application can still be reached (for a while) even if the
user's session on the keycloak server <br>
has been terminated.<br>
