I have added module.xml in location
keycloak-2.5.0.Final/modules/system/layers/base/io/netty/main. Not sure if
thats the correct location.

in my module.xml I have added as

<module name="sun.jdk">
<imports>
<include path="sun/misc/Unsafe" />
</imports>

Still I am getting same error. Please help with this.


Thanks,
Deepu
