java warning: Varargs method could cause heap pollution from non-reifiable varargs parameter

Question

I am using IntelliJ IDEA with javac on JDK 1.8. I have the following code:

class Test
{
    @SafeVarargs
    final void varargsMe         


        

Answer 1

An additional (and quite superfluous-looking) @SuppressWarnings( "varargs" ) is needed to suppress the warning, as follows:

@SafeVarargs
@SuppressWarnings( "varargs" )
final void varargsMethod( Collection... varargs )
{
    arrayMethod( varargs );
}
