Bumps com.google.errorprone:error_prone_core from 2.50.0 to 2.52.0.

Release notes

Sourced from com.google.errorprone:error_prone_core's releases.

Error Prone 2.52.0

New checks:

• AlmostExhaustiveTestParameter: Prefer an exhaustive @TestParameter with an assumption to filter out specific enum values, so newly added enum values are automatically tested (disabled by default).
• SingleTestParameter: Suggest @TestParameter on the parameter instead of @TestParameters when there is only one test parameter, replacing PreferTestParameter (disabled by default).
• SingleValueTestParameter: Suggest replacing a @TestParameter that has only a single value with a local variable in the test method (disabled by default).
• ValueClassEquals: Require non-record concrete value classes to explicitly override equals and hashCode.

Other changes:

• LoopToTestParameter: Changed severity to SUGGESTION (disabled by default).
• DistinctVarargsChecker: Allow duplicate arguments to Iterables.concat (#6239) and Mockito argument matchers such as any() (#6240).
• UnusedVariable: Treat fields accessed via MethodHandles.Lookup (VarHandle/getter/setter lookups) or Atomic*FieldUpdater.newUpdater as used.
• StringBuilderInitWithChar / StringBuffer refactoring: Refactor StringBuffer to StringBuilder even when used with Matcher.appendReplacement and appendTail (when supported by the target JDK or Android minSdkVersion).
• CompileTimeConstant: Treat record and interface fields and field accesses on compile-time constants (compileTimeConstant.compileTimeConstantField) as compile-time constants.
• ValueClassIdentity / ReferenceEquality: Handle JEP 401 value classes.
• FieldCanBeFinal / ThreadSafety: Improve compile-time performance on large classes and deep type hierarchies, and update SafeRE to 1.1.0 (#6230).
• Added ClassName for caching resolved ClassSymbol, Type, and binary Name lookups across a compilation.

Closed issues: #5964, #6165, #6230, #6239, #6240, #6275

Full changelog: google/error-prone@v2.51.0...v2.52.0

Error Prone 2.51.0

New checks:

• HashCodeInObjectsHash: Detect redundant hashCode() or Objects.hash() calls inside Objects.hash(...), and simplify single-argument Objects.hash(x) calls to Objects.hashCode(x).
• LoopToTestParameter: Suggest migrating loops in unit tests to TestParameterInjector.
• MissingJavadoc: Flag public types that are missing Javadoc comments (disabled by default).
• PreferCharsetOverload: Prefer calling method and constructor overloads that accept a Charset over those that accept a String encoding name.
• PreferPreconditions: Suggest using Guava's Preconditions instead of explicit if-throw statements for parameter validation (disabled by default).
• RequireNonNullRefactoring: Refactor explicit if (x == null) { throw new NullPointerException(...); } checks to Objects.requireNonNull (disabled by default).
• SimplifyTestParameter: Remove redundant explicit value lists on @TestParameter annotations for boolean and Enum types when all values are specified (disabled by default).
• TraditionalJavadocToMarkdown: Convert traditional /** ... */ Javadoc comments into /// Markdown Javadoc comments (disabled by default).
• ValueClassIdentity: Flag reliance on identity semantics (such as synchronization, WeakReference, IdentityHashMap, or System.identityHashCode) of value-based classes (disabled by default).

Other changes:

• CompareToZero: Upgraded from warning to error, and expanded to flag non-relational operations, unary negation, and switch statements/expressions on compareTo and compare results without Integer.signum.
• IfChainToSwitch: Enabled by default as a warning.
• UndefinedEquals: Merged ArrayAsKeyOfSetOrMap and CollectionUndefinedEquality into UndefinedEquals (retaining their names as altNames), and generalized detection of types without well-defined equals or hashCode across direct equality, collection containment, and hash-based containers.
• EqualsIncompatibleType / TruthIncompatibleType: Flag equality comparisons between distinct record types (#6107).
• ReferenceEquality: Allow == comparisons on private classes whose type hierarchy does not override Object.equals (#5865), private static final sentinel fields, Thread (#5900), and com.sun.source.tree.Tree.
• PatternMatchingInstanceof: Support while and for loops, parenthesized expressions (#5843), and replacing additional redundant casts when the instanceof already introduces a pattern variable.
• DistinctVarargsChecker: Expanded to check Objects.hash, CompletableFuture.allOf/anyOf, EnumSet.of, Sets.union/intersection/difference, Stream.concat, Math.min/max, and additional JDK, Guava, Protobuf, Truth, and Mockito methods.
• MustBeClosedChecker: Require java.lang.foreign.Arena.ofConfined and Arena.ofShared to be closed.
• ImpossibleNullComparison: Flag null checks on the return value of Class.forName.
• RestrictedApi / RestrictedInheritance: Added an allowedPaths attribute to allow calls or inheritance from matching file paths without a regular expression.
• InlineMeInliner: Support substituting type arguments at call sites when inlining generic @InlineMe methods.
• WellKnownKeep: Recognize Apache Beam DoFn annotations and retain open-source library annotations (Gson, Mockito, Guice, Objectify, TestParameterInjector, AutoFactory).

The change upgrades the inherited Maven Error Prone compiler dependency from 2.50.0 to 2.52.0 while retaining the existing NullAway configuration; no concrete regression was identified. I did not run a local build, and the supplied CI snapshot includes successful Java matrix checks alongside pending reruns and an earlier failed quality-gates run whose logs were unavailable.
