When attempting to connect to a DataSource that specifies a database
that doesn't exist, Tomcat 8.5.46 throws an informative SQLException;
for example: java.sql.SQLException: Cannot create
PoolableConnectionFactory (FATAL: database "labkey19.3" does not exist)
In the same situation, Tomcat

It isn't.
Hi Anthony
Have you turned debug logging on to see what it is picking up as modified?

Thanks for your responses.
I understand that re-reading the static files is not optimal, but how does
reading files from the jar affect them being reloaded... In Tomcat 7, that
seemed to prevent the jars from being reloaded since the accessTime was
changed; in Tomcat 8, it seems the modified()

Not sure if this is the context reload trigger... i.e. the

Mostly, we are talking about the default class loader; however, the application
Just noticed another thread on this topic: RE: Tomcat discards and reloads the

Setting the Engine attribute backgroundProcessorDelay to 90s does reduce the

In the last few months we migrated our web application from Tomcat 7.0.55 to

Hello,
The web application is trying to load specific classes from the jar files.
