C2 misses inlining opportunity and issues a method call for an unreachable call site.
It occurs only for direct calls. It may lead to missed optimization opportunities and suboptimal performance.

Test case:
public class Test {
    private static final int ARRAY_LENGTH = 100000;

    public int value;
    void inc() { value++; }

    public static Test[] testFieldCall(int incCount) {
        Test[] a = new Test[ARRAY_LENGTH];

        for (int i = 0; i < ARRAY_LENGTH; i++) {
            a[i] = new Test();
        }

        while (incCount-- > 0) {
            for (int i = 0; i < ARRAY_LENGTH; i++) {
                a[i].inc();
            }
        }

        return a;
    }

    public static void main(String[] args) {
        Test[] result = new Test[0];

        while (true) {
            result = testFieldCall(1000);
        }
    }
}

Compilation log is the following:
    100 4 % Test::testFieldCall @ 8 (62 bytes)
                            @ 20 Test::<init> (5 bytes) inline (hot)
                              @ 1 java.lang.Object::<init> (1 bytes) inline (hot)

LogCompilation says the following:

and for the call site at Test::testFieldCall @ 48:

<bc code='182' bci='48'/>
<method id='753' holder='749' name='inc' return='655' flags='0' bytes='11' compile_id='5' compiler='C2' iicount='15377'/>

However all invocations of Test::inc went throught Test::testFieldCall @ 48.
