Hi,
Also, just wondering if this has already been noted, if it's just me (possibly
due to
Oracle Java 11), or if this is a valid bug. If this is ignorable I'm fine with
that,
i.e., it's seemingly not affecting anything I'm doing.
I'm running Ubuntu 22.04.1 LTS on an HP Envy laptop, Intel® Core™ i7-8550U CPU
@ 1.80GHz × 8,
► java -version
java version "11.0.14" 2022-01-18 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.14+8-LTS-263)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.14+8-LTS-263, mixed mode)
On restarting Tomcat I always see this stack trace in the logs:
---------------------- catalina.out stack trace ----------------------

The rice leaves in the garden
Rustle in the autumn wind
That blows through my reed hut.
