cfml

hi,
anyone have any idea why i get this error?
i just updated lucee to version 5.3.9.141

```net.sf.ehcache.CacheException Error
java.io.InvalidClassException: lucee.runtime.db.SQLItemImpl; local class incompatible: stream classdesc serialVersionUID = 2329505848848154278, local class serialVersionUID = 5096074495166317863 ```

I solved with `&lt;cfobjectcache type="query" action="clear"&gt;` (I could not find the "clear query cache" button in the admin area).

Every time I update Lucee it's a lottery... :slightly_frowning_face:

That probably just means serialized Java objects in a cache aren't compatible across versions of Lucee if Lucee changes the serialized class.

I'd put in a ticket to see if Lucee can handle this more gracefully (like removing the item from the cache), but you'd also need to show just exactly what object you are caching.

ive had this issue between versions before, definitely need to clear items from cache after the update
