DontCallThreadRun

Explicitly calling Thread.run() method will execute in the caller’s thread of control. Instead, call Thread.start() for the intended behavior.

        ./Name[ends-with(@Image, '.run') or @Image = 'run']
        and substring-before(Name/@Image, '.') =//VariableDeclarator/VariableDeclaratorId/@Image
        [../../../Type/ReferenceType[ClassOrInterfaceType/@Image = 'Thread']]
        or (
        ./AllocationExpression/ClassOrInterfaceType[@Image = 'Thread']
        and ../PrimarySuffix[@Image = 'run'])
    ]
]


Example(s):



Thread t = new Thread();
t.run();            // use t.start() instead
new Thread().run(); // same violation
