Hi,
I've searched for a solution on wiki, web, apache pony mail lists. Tried
various experinetns to isolate the cause... but unsuccessful. I've seen this 3
months ago with 9.0.93 then waited to more tomcat releases and retry thinking
it is maybe something temporary. It isn't. Currently, an experienced webdev is
investing this but we have no clue what causes this.
We have a mature product called Continuity Engine which bundles tomcat 9 for
quite a few years. We perform quarterly tomcat 9 updates. And all were
successful until and including tomcat 9.0.91.
Issue:
- during first start of tomcat 9.0.96 while our hbws.war webapp is deployed,
following error is thrown.

A subsequent restart fixes the situation. But or our product bundling tomcat,
restart is an showstopper.

- last version that worked at our end was 9.0.91
- since then we've seen this with 9.0.93, 9.0.96, without doing any changes to
our side of the code. In other words,
Something seemed to be changed in releases post 9.0.93 which causes this
behavior at our end.

Would somebody provide a pointer or a direction I should start looking into?
Your help would be really appreciated.
