merlimat opened a new pull request, #25431:
URL: https://github.com/apache/pulsar/pull/25431
## Motivation
Fix `unchecked` compiler warnings in test code — unchecked casts and generic
array creation due to type erasure.
This is part of a series to clean up test compile warnings (following
production code cleanup in #25414-#25422).
## Changes
- Add `@SuppressWarnings("unchecked")` at method or variable level for
unavoidable Mockito mock casts (type erasure prevents parameterized mock casts
at runtime)
- Use `doReturn().when()` instead of `when().thenReturn()` where wildcard
capture causes unchecked warnings
- Add `@SafeVarargs` for varargs utility methods that only read from the
array
- Fix generic array creation warnings in test utility methods
Affects ~213 files across all modules.
## Verifying this change
- `./gradlew compileTestJava` passes cleanly
- `unchecked` warning count drops to zero
