Subject: [PATCH 3/3] =?UTF-8?q?feat:=20Java=2021=20modernization=20?=
=?UTF-8?q?=E2=80=94=20wms?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Diamond operator (<>): 16 redundant type arguments removed across 5 files
- Pattern matching instanceof: 3 casts eliminated (Capabilities.java, WMSTiledImageLayer.java)
- Lambda expression: 1 anonymous RetrievalPostProcessor replaced (Capabilities.java)
- StringBuffer → StringBuilder: 2 local-scope usages converted (Request.java, WMSTiledImageLayer.java)
- Raw-type cast cleanup: 5 unnecessary (Map.Entry) casts removed (Request.java)
No public API changes. Build verified with JDK 21.
