Fail to restart with h2 -- ubuntu tw 8.4

With a fresh install using the textual installer using all defaults.

if I run

$ catalina.sh stop
$ catalina.sh start

I get the error:

*** CRITICAL ERROR ON STARTUP: Improper value found for model provider configuration password, system cannot start without valid password
*** Web Application STATE is being set to ERROR! ***

If I destroy the VM and reinstall, foundation runs fine after the install. But any attempt to restart will not start.

The config for h2 (created by the installer) contains

"PersistenceProviderPackageConfigs": {
 "H2PersistenceProviderPackage": {
 "ConnectionInformation": {
 "password": "\u003caddsecurepassword\u003e",
 "username": "twadmin"
 }
 }
 },

(This is after finishing up the install of the analytics server, so it would really suck to have to start all over again)
