Verify portal is a sponsor or self-reg portal (not Hotspot). I can think of a few settings that may trigger including Web Agent and DHCP renewal applet...

I would say that it's not recommended to use ip release /renew feature on the guest portals. The support for this has faded from browsers.
This relies on Java and the only browser I know that currently supports this is internet explorer. If a guest uses Chrome, Firefox, or safari, then they will have problems.
I worked with tac recently and filed a new bug in 2.4 because this feature is not working anymore. Something has changed and the coa/vlan change is not applying after the first guest login. You log in a second time and the vlan change applies.

Agree this option is not generally recommended. Question was more specific to Java warning and what may have triggered it. For reasons cited, it would be better to avoid any VLAN change for web auth flow (no supplicant to detect VLAN change). For wireless it may be possible to assign a new interface which shares same IP address space, or use ACLs or SGTs to apply different traffic policy without flipping VLANs/subnets.

Actually I had this turned on "Enable VLAN DHCP release" and the solutions was to turn it off. I must have been playing with settings and forgot to revert it back to default which is off by default..
