- app/WEB-INF/lib/javax.mail-1.6.0.jar
- app/WEB-INF/lib/mail-1.4.jar
QA environment hardware properties:
Mem: 6809

CPU op-mode(s):32-bit, 64-bit
CPU(s): 2
Model name: Intel(R) Xeon(R) CPU E7-4850 v4 @ 2.10GHz

In my QA env tomcat class loaders use javax.mail-1.6.0.jar for method
javax.mail.Authenticator
[23.922s][info][class,load] javax.mail.Authenticator source:
file:/tomcat-9.0.54/webapps/app/WEB-INF/lib/javax.mail-1.6.0.jar
but in my Prod env tomcat use mail-1.4.jar for same method
[12.306s][info][class,load] javax.mail.Authenticator source:
file:/tomcat-9.0.54/webapps/app/WEB-INF/lib/mail-1.4.jar
Do you know why Tomcat class loader use different libs in two different
environments?
Do you have best practices to force tomcat to always use the latest libs in
different environments?
The libraries are not loaded in any particular order. The difference you
are seeing is the order that the filesystem is returning the files when
a directory-scan is being done. It's totally arbitrary and unpredictable
unless you understand how the filesystem organizes files. It can even
change due to other factors than just e.g. updating a file or changing
its timestamp.
Please see https://bz.apache.org/bugzilla/show_bug.cgi?id=57129 for lots
more information.
