fix: suppress Java compilation warnings in http-core, http and http-jackson
(#1118)
Motivation:
Several Java source files in pekko-http produce compilation warnings:
- ContentTypes.java references deprecated Scala ContentTypes APIs
- AttributeKeys.java contains unchecked casts from Scala to Java
AttributeKey
- Coder.java uses deprecated internal Scala coding objects (NoCoding$,
Deflate$, Gzip$)
- Jackson.java references deprecated APIs
- ParserSettingsTest.java tests deprecated API overloads
Modification:
- Add @SuppressWarnings("deprecation") to ContentTypes, Coder, Jackson
and ParserSettingsTest
- Add @SuppressWarnings("unchecked") to AttributeKeys
Result:
Java compilation no longer reports warnings for these files. All
suppressions are on code that intentionally uses these APIs for Java
interoperability.
Tests:
Not run - full pekko-http clean compile requires h2spec_darwin_amd64
dependency that is unavailable on macOS ARM64. The changes are
annotation-only and cannot affect runtime behavior.
References: None - cleanup
