Release Notes

google/error-prone (com.google.errorprone:error_prone_core)

v2.28.0: Error Prone 2.28.0

Error Prone nows supports the latest JDK 23 EA builds (#​4412, #​4415).

Closed issues:

• Improved errors for invalid check severities (#​4306).
• Fix a crash with nested instanceof patterns (#​4349).
• Fix a crash in JUnitIncompatibleType (#​4377).
• In ObjectEqualsForPrimitives, don't suggest replacing equal with == for floating-point values (#​4392).

New checks:

• DeeplyNested discourages very deeply nested code that can cause StackOverflowErrors during compilation.
• GuiceNestedCombine discourages nesting of Modules.combine(), which is unnecessary.
• PatternMatchingInstanceof migrates code to use pattern matching for instanceof
• SunApi discourages use of internal proprietary JDK APIs which may be removed from future releases.
