And does it seem to prevent the Redis cache from working?

java.base/java.lang.Thread.run(Unknown Source) Caused by: lucee.commons.lang.ClassException: java.lang.reflect.InvocationTargetException while creating an instance of ortus.extension.cache.redis.RedisCache ... 86 more

The situation when it happens: on our ci server we stop the IIS sie and the lucee instance. wait for the instance to be realley stopped using the command

box server status name=ci property=status

new code gets deployed. we start lucee we call a status cfm page on localhost to check if the application has started. It's a .cfm file with "OK" as content. then we start the iis site. then we call a .cfm page with the purpose to clear the cache items. For now the error seems to happen on the line that clears the query cache

cacheRemoveAll("QUERY");

Before that the "OBJECT" cache and 3 custom cache regions have already been cleared

I want to make sure there are no more "caused by" bits at the end

That error seems to be coming from Lucee itself

The code that is throwing the error is not from our extension

I would guess Lucee hasn't loaded the OSGI bundles properly, but it's hard to say

There could be another related exception that is causing the failure that is not getting logged.

I'm not really sure what

InvocationTargetException while creating an instance of xx

really means in this case

Can you check the logs for any previous errors-- sometimes when a class can't be created (the constructor errors), the JVM will throw a less helpful message and not even try on all subsequent attempts.

That could be what's happening here, and the "real" error could be up above in your logs (if it was loggeed)

weird. in the application.log I see 4 lines after a restart of lucee "INFO","XNIO-1 task-1","08/05/2022","133438","application","Redis Cache [userinfo] accepted, connection built and ready to rock" "INFO","XNIO-1 task-1","08/05/2022","133438","application","Redis Cache [statistics] accepted, connection built and ready to rock" "INFO","XNIO-1 task-1","08/05/2022","133438","application","Redis Cache [methodinfo] accepted, connection built and ready to rock" "INFO","XNIO-1 task-1","08/05/2022","133438","application","Redis Cache [OBJECT] accepted, connection built and ready to rock" I'm missing the line that should sat "Redis Cache [QUERY] ready..." The invocation error happens on the the line where we want to clear the query cache.

Also when I run a page twice with a queryExecute , with a cachedWithin parameter, and dump the result. the second time it says the query was cached, but I don't see a new item in Redis. It looks like the query cache connection was not created.
