[jdk17u] RFR: 8273375: Remove redundant 'new String' calls after concatenation in java.desktop

[Olga Mikhaltsova]

I'd like to backport JDK-8273375 to jdk17u.
The original patch applied cleanly.
The fix removes unnesessary 'new String' calls because the result of strings' concatenation is already a newly created String object.
