V6064. Suspicious invocation of Thread.run().

Dec. 14, 2018

The analyzer has detected a suspicious direct call of Thread.run(). Invoking a thread in a way like that may be confusing. When calling the run() method of the Thread object directly, all operations contained in the body of run() will be executed in the current thread rather than the newly created one.

Consider the following example:

private class Foo implements Runnable
{
  @Override
  public void run() {/*...*/}
}

....

Foo foo = new Foo();
new Thread(foo).run();
....

In this code, the body of the run() method will be executed in the current thread. Does the programmer really expect this? To have the body of the run() method execute in the new thread, use the start() method.

Fixed code:

private class Foo implements Runnable
{
  @Override
  public void run() {/*...*/}
}

....

Foo foo = new Foo();
new Thread(foo).start();
....
