  • NonImplicitExceptionDominatorsAnalysis introduced (API consistency)

Added

• Rule DCN_NULLPOINTER_EXCEPTION covers catching NullPointerExceptions in accordance with SEI Cert rule ERR08-J (#​1740)
• Multiple types of report can be generated in batch. Set multiple commandline options for report configuration like -html=report/spotbugs.html -xml:withMessages=report/spotbugs.xml.
• New rule REFL_REFLECTION_INCREASES_ACCESSIBILITY_OF_CLASS to detect public methods instantiating a class they get in their parameter. This rule based on the SEI CERT rule SEC05-J. Do not use reflection to increase accessibility of classes, methods, or fields. (#SEC05-J)
• New detector FindOverridableMethodCall to detect invocation of overridable method in constructors (MC_OVERRIDABLE_METHOD_CALL_IN_CONSTRUCTOR) and clone() method (MC_OVERRIDABLE_METHOD_CALL_IN_CLONE), according to SEI CERT rules MET05-J. Ensure that constructors do not call overridable methods and MET06-J. Do not invoke overridable methods in clone().
• Translation of online manual to Brazilian Portuguese (PT-BR).

Fixed

• False negative about the rule IM_MULTIPLYING_RESULT_OF_IREM ([#​1498])(https://github.com/spotbugs/spotbugs/issues/1498)

Deprecated

• -output commandline option is deprecated. Use commandline options for report configuration like -xml=spotbugs.xml instead.
