(This should perhaps be closed as won't fix ?)

Note that asymmetry in javac's treatment between argv array and the pattern binding variable array.

public class X {

    public static void main(String args[]) {
        Object o = null;
        if (o __matches String x []) {
        }
    }
}

This program fails to compiler and elicits the following:

/home/srikanth/tmp/X.java:5: error: ')' expected
        if (o __matches String x []) {
                                ^
/home/srikanth/tmp/X.java:5: error: illegal start of expression
        if (o __matches String x []) {
                                 ^
2 errors
