remove maven-compiler warnings with target Java 17

[baulea]

Although the project code is not runnable with JDK17 at the moment, I would like to fix some warnings the Java 17 compiler shows up. The changes are compatible with Java 8.

I would appreciate if you assign this issue to me.

Hi @authorjapps, the PR #604 could be merged into master. It is fully compatible with JDK8.

Hi @authorjapps, is there anything else I should do? Or are we just waiting for a reviewer to review the PR?
