Description Oyvind Harboe CLA 2004-11-09 05:50:35 EST 
How can I get rid of the warning in the code below?



import java.util.ArrayList;

public class Foo
{
	public void bar()
	{
		ArrayList<Byte> x=new ArrayList<Byte>();
		
		ArrayList<Byte> y=(ArrayList<Byte>)x.clone();
	}
}

Remove parameterization from cast type, since the compiler tells you it is
irrelevant at runtime.

import java.util.ArrayList;

public class X
{
	public void bar()
	{
		ArrayList<Byte> x=new ArrayList<Byte>();
		
		ArrayList<Byte> y=(ArrayList)x.clone();
	}
}

Not a bug, also javac -Xlint issues a similar warning.
