Fix new PMD warnings

[stoecker]

After PMD upgrade a bunch of new warnings cam up.

Anyone time to help fixing them?

Anyone time..?

I don't have any at the moment, but hopefully I will have some in the following weeks.

Sorry, the recent changes caused another build failure in my Eclipse installation, so atm I try to fix that.

[stoecker]

I found that an "svn cleanup --remove-ignored" helped. I had to do this for the CI to work.

Also note, that while I tried to keep downwards compatibility intact I may have created some places where Java >= 21 is required. I don't plan to actively search such issues as long as the JOSM server stuff for the needed builds does still work with Java 11.

My problems with Eclipse are fixed. No idea what exactly was wrong, it used an older version of the compression library.

Where do I see the bunch of PMD warnings?

[GerdP]

Ah, didn't use svn update today. Now I see when running ant pmd

Replying to GerdP:

That's the reason why I don't use eclipse. That "No idea why" happened too often to me...

I can take care about the "Public member ... declared in a non-public type" messages. My understanding is that I just have to remove the public key word.

Or change to "protected"? I'm not totally sure. Had only a short look at the PMD description.

[GerdP]

In ​https://github.com/pmd/pmd/pull/6231 I see that either public should be removed or private should be added.
Anyhow there seem to be more to this because when I change the flagged places in src\org\openstreetmap\josm\data\coor\Coordinate.java I can no longer compile. Not yet sure if this is a PMD error or if I have to change more code.

In 19520/josm:

ignore rule PublicMemberInNonPublicType, see #24635
