Call to a 'native' method while locked

Last modified: 03 December 2024

Reports calls native methods within a synchronized block or method.

When possible, it's better to keep calls to native methods out of the synchronized context because such calls cause an expensive context switch and may lead to performance issues.

Example:

native void nativeMethod();

void example(){
  synchronized (lock){
    nativeMethod();//warning
  }
}
