Compatibility of some modules with java 8/11

[ta7tou7]

Hello,

I'm working on a java 11 project, I tried to use prometheus-metrics-exporter-servelet-jakarta module with the last version 1.3.6
but unfortunately it seems that this module is compiled with java 17, while other modules with the same versions are compiled with java 8

Is it something expected ? and how should I proceed to use this module in my project ?

#1360 showed you get warnings, because the jakarta libraries are not compatible with java 8

Warning:  Cannot find annotation method 'forRemoval()' in type 'java.lang.Deprecated'
Warning:  Cannot find annotation method 'since()' in type 'java.lang.Deprecated'

Is this causing a problem for you?
