Problem

In a Play project, the Play resolver handles every A.b reference, both in route files and in ordinary Java/Scala calls, at 0.9. For a method, it takes the first method with that name anywhere in the class's file, not in the class. So in a file with several classes, such as Http.java or a Scala file with sibling objects, the first same-named method wins, whichever class declares it:

• AuthorityPort.parse(...) → RequestAuthority::parse or another sibling's parse
• HttpEntity.Strict(...) from Scala → the Java HttpEntity::Strict constructor
• a route controllers.Foo.index → a nested Foo::Helper::index declared first in the file

Fix

A method counts only if its qualified name is exactly <class qn>::<method>. Nested classes follow from that, and a Scala companion object shares its class's qualified name. Inherited members aren't looked up, because supertypes aren't known on the first pass, so the resolver declines instead of guessing and the generic resolver handles the reference.

Measured on playframework (main ba3c21e vs this branch; every edge checked by hand)

• 114 lost. About 98 were wrong:
  • ~33 AuthorityPort::parse;
  • 27 HttpEntity.Strict/Streamed/Chunked Java constructors reached from Scala;
  • 10 F.Tuple constructors;
  • ApplicationLoader/Context.create crossing Java and Scala;
  • self-loops;
  • 5 wrong route handlers.
• 13 true edges lost: inherited members, Assets.versioned/resourceNameAt (the object extends AssetsBuilder) and Helpers.await/call/flash/session. The old first-in-file rule reached these by accident. Recovering them needs a supertype walk in a later pass.
• 73 gained, 70 of them correct: RequestAuthority::parse/parseOrThrow (~36), the F::Tuple factory, the right ApplicationLoader.create owners, FormController::index, Clients::show, and others.

Tests

__tests__/frameworks-integration.test.ts gets three cases: a Java nested class (Http.Cookie/MediaType.parse), Scala sibling objects (Scheme/AuthorityPort.parse), and a route whose file declares a nested Helper.index first. Each failed on main and passes now. The full suite passes.

Thank you @danusha2345! This landed as #2875 with your authorship. Play's Class.method references now reach the named class's own member instead of the first same-named method in its file, which fixed hundreds of edges in playframework and CMAK.

Since Java records are now indexed (#2868), Play's RequestAuthority exists as both a Scala case class and a Java record, so we added a preference for the caller's own language. We also made Scala objects and Java interfaces owners, and the call now picks the overload its arguments fit, and the caller's own file among same-named objects. The details and the two known follow-ups (playframework's AssetsSpec, and Scala files that import Play's Java classes) are in the PR description. Closing this in favor of #2875, which is now merged.
