SpotBugs 4.10.0-SNAPSHOT

CHANGELOG

Refactor

• Move internal usage of 'javax.annotation.Nonnull' to 'jakarta.annotation.NonNull'. (#3858)
• Move internal usage of 'javax.annotation.Nullable' to 'jakarta.annotation.Nullable'. (#3861)
• Renamed methods from edu.umd.cs.findbugs.SwitchHandler to reflect that they return a PC, not an offset (#3869)
• Make the progress bar more visually appealing by adding some borders (#3896)
• Reuse DismantleBytecode.isIf introduced in (#3869)

Added

... (truncated)

Sourced from com.github.spotbugs:spotbugs-annotations's changelog.

4.10.1 - 2026-06-08

• 4.10.0 was not released due to a release process error (artifacts were built from a -SNAPSHOT version). 4.10.1 is the corrected release and contains the intended 4.10.0 contents.

4.10.0 - 2026-06-07

Refactor

• Move internal usage of 'javax.annotation.Nonnull' to 'jakarta.annotation.NonNull'. (#3858)
• Move internal usage of 'javax.annotation.Nullable' to 'jakarta.annotation.Nullable'. (#3861)
• Renamed methods from edu.umd.cs.findbugs.SwitchHandler to reflect that they return a PC, not an offset (#3869)
• Make the progress bar more visually appealing by adding some borders (#3896)
• Reuse DismantleBytecode.isIf introduced in (#3869)

Added

• Add partial support for org.jspecify.annotations.Nullable, org.jspecify.annotations.NonNull, org.jspecify.annotations.NullUnmarked and org.jspecify.annotations.NullMarked annotations. These are aliased to the closest existing SpotBugs nullness annotations. This is not a complete implementation of the JSpecify spec; scope-level semantics of @NullMarked and @NullUnmarked are not yet supported. (#3996)
• Recognize jakarta.annotation.Nonnull and jakarta.annotation.Nullable (#3780)
• Detect use of sun.misc.Unsafe and jdk.internal.misc.Unsafe (#3804)
• New bug type is introduced: NCR_NOT_PROPERLY_CHECKED_READ. Improper validation of the return value from the read() method in InputStream and Reader classes may result in an array not being fully filled. (#3766)
• New detector FindImproperSynchronization and introduced new bug types:
  • USO_UNSAFE_METHOD_SYNCHRONIZATION is reported when using synchronized methods with the class' accessible intrinsic lock,
  • USO_UNSAFE_STATIC_METHOD_SYNCHRONIZATION is reported when using static synchronized methods with the class' exposed intrinsic lock,
  • USO_UNSAFE_OBJECT_SYNCHRONIZATION is reported when the lock used for synchronization is visible from the outside,
  • USO_UNSAFE_ACCESSIBLE_OBJECT_SYNCHRONIZATION is reported when the lock used for synchronization is made accessible, with methods that update or return the lock, to the outside,
  • USO_UNSAFE_INHERITABLE_OBJECT_SYNCHRONIZATION is reported when the lock used for synchronization is can be altered by subclasses,
  • USO_UNSAFE_EXPOSED_OBJECT_SYNCHRONIZATION is reported when the lock used for synchronization is later exposed in the subclasses.
  • USBC_UNSAFE_SYNCHRONIZATION_WITH_BACKING_COLLECTION is reported when the backing collection of a lock is visible from the outside,
  • USBC_UNSAFE_SYNCHRONIZATION_WITH_ACCESSIBLE_BACKING_COLLECTION is reported when the backing collection of a lock is made accessible, with methods that update or return the lock, to the outside,
  • USBC_UNSAFE_SYNCHRONIZATION_WITH_INHERITABLE_BACKING_COLLECTION is reported when the backing collection of a lock can be altered by subclasses. (See SEI CERT rule LCK00-J and SEI CERT rule LCK04-J)
• New detector FindIncreasedAccessibilityOfMethods for new bug type IAOM_DO_NOT_INCREASE_METHOD_ACCESSIBILITY. This detector reports a bug if a class increases the accessibility of overridden or hidden methods. (See SEI CERT rule MET04-J)

Fixed

• Fix DM_STRING_TOSTRING false negative when toString() is chained before a method call (e.g., s.toString().toLowerCase()); multiple occurrences in the same method are now all reported (#3966)
• Stop exposing JUnit BOM as a transitive dependency to consumers (#3908)
• Fix incorrect bug counts and sizes when unioning reports (#3721)
• Classes containing only methods throwing UnsupportedOperationException with setter-like names are no longer considered as mutable (#1601)
• Enhanced SARIF output with full description sections - adding markdown is still an open issue (#2339)
• Added missing null check to MultipleInstantiationsOfSingletons detector (#3823)
• Fix invalid syntax in findbugsfilter.xsd (#3832)
• Fix CT_CONSTRUCTOR_THROW FP with public and private constructors (#3822)
• Fix tool name in usage info, (#3847)
• Fix the building of relative chains of ./././ in filenames in fbp files (#3852)
• Fix IllegalArgumentException initializing spotbugs when inside a fat jar on Java 25 (#3875)
• Do not report DM_DEFAULT_ENCODING for classes compiled with target >= 18 (#3866)
• Fix FS_BAD_DATE_FORMAT_FLAG_COMBO not suppressed by field-level annotation (#3838)
• Fix SF_SWITCH_FALLTHROUGH false positives (#3767)
• Recognize well-known exception-throwing utility methods when looking for exceptions thrown from constructors (#3821)
• Fix RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE false negative when non-null value is on the left side of null comparison (#3920)
• Fix IM_BAD_CHECK_FOR_ODD false negative when using Yoda-style comparison (1 == i % 2) (#3886)
• Fix PluginLoader.close() to continue closing all URLClassLoaders when one close operation fails, suppressing subsequent IOExceptions. (#3958)
• Fix broken bugDescriptions.html#TYPE links by restoring legacy bug type anchors in generated docs (#2113)
• Fix EI_EXPOSE_REP false negative in package-private classes that expose mutable state through methods overriding a public super-type (#4027)
