I was able to work around it on 17.0.13 by adding --add-opens=java.base/
java.io=ALL-UNNAMED to my startup script.

Hello again
I sent the following message yesterday. Is anyone going to reply? I'm
totally stuck. If no one can help, then I will have no alternative but to
abandon Tomcat and try some alternative.

Hello,
I'm trying to set up MySQL 8.0.11 database connection pooling in Tomcat
10.1.24 on Windows 10. The MySQL database is "holidays" with user name
"root" and password "rootpwd". I've tried to follow the examples at
https://tomcat.apache.org/tomcat-9.0-doc/jndi-datasource-examples-howto.html
:)

Thank you so much.
I am ashamed that I did not read the documentation carefully.

Hi, community
When I configured Tomcat logs, I found the following configuration in
logging.properties
1catalina.org.apache.juli.AsyncFileHandler
2localhost.org.apache.juli.AsyncFileHandler
3manager.org.apache.juli.AsyncFileHandler
4host-manager.org.apache.juli.AsyncFileHandler
I am not sure wha
Christ,
Thanks for the explanation.
The XML-based registration - is that something I would do as a user, or
something that would be changed on the Tomcat side as part of its release
bundle?

All,
I've been doing some testing, and I'm pretty sure the addSslHostConfig
operation on ProtocolHandler is busted in 9.0.83.
In versions prior to 9.0.82, you can call the operation with a single
argument of type SSLHostConfig.
In 9.0.82, that contract seems to have been broken, and you had to ca
(DefaultMBeanServerInterceptor.java:814)
~[?:?]
at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:802)
~[?:?]
Any ideas here?

I found the source of the problem
9.0.82 accepts the simple class name as a type parameter for the operation.
9.0.83 requires the canonical class name.

Is this a regression, or was this an intentional change?

losed or similar? maybe by knowing the
closed ones vs open ones, we can figure out the keep-alive ones.
Any insight will be appreciated.
