Class AvoidDoubleBraceInitializationCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable

    public class AvoidDoubleBraceInitializationCheck
    extends AbstractCheck

    Detects double brace initialization.

    Rationale: Double brace initialization (set of Instance Initializers in class body) may look cool, but it is considered as anti-pattern and should be avoided. This is also can lead to a hard-to-detect memory leak, if the anonymous class instance is returned outside and other object(s) hold reference to it. Created anonymous class is not static, it holds an implicit reference to the outer class instance. See this blog post and article for more details. Check ignores any comments and semicolons in class body.
