The method traceMethodCalls(boolean) is undefined for the type Runtime-CodePudding

I get the error:
(Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method traceMethodCalls(boolean) is undefined for the type Runtime)
when I run the code Below.

    public static void main(String[] args) {
        //Start tracing for instructions
        System.out.println("Enabling...");

        Runtime.getRuntime().traceMethodCalls(true);
        System.out.println("Enabled");
    }
}

CodePudding user response：

This method was removed in Java 13.

See the release notes: https://www.oracle.com/java/technologies/javase/13-relnote-issues.html

The obsolete methods traceInstructions(boolean) and traceMethodCalls(boolean) have been removed from the java.lang.Runtime class. These methods have been non-functional for many releases, and their intended functions are provided by the Java Virtual Machine Tool Interface (JVMTI).

CodePudding user response：

The traceInstructions and traceMethodCall methods have not done anything useful since Java 1.2.1 !!

See https://bugs.openjdk.java.net/browse/JDK-4623283

The methods were marked as deprecated (for removal) in Java 9 and finally removed in Java 13.
