Suggestion issue for Variable Arity Parameters

[stanNthe5]

Example code:

class Test {
    static Foo foo = new Foo();
    static Foo bar = new Foo();

    void test(Foo... foo) {
    }

    void test2() {
        test(|); // cursor at "|"
    }
}

When the cursor is in the "test()", and trigger suggestions using shortcut, "foo" and "bar" will appear in a dropdown list for selection, there is no problem. After choosing one,the code is:

test(foo,|) ; // cursor at "|"

Now when I try to trigger suggestion, "foo" and "bar" not appear.

Indeed completion doesn't work immediately after the ,. Eclipse actually exhibits the same behavior, so this is an upstream issue.
However, completion works if you add a space after the comma, like :

test(foo, |) ; // cursor at "|"

Completion after a comma and space shows all suggestions(including incorrect suggestions). Only the first completion is correct. I'm using VScode.

This is fixed and will be part of the next nightly build.

Fix now available in pre-releases. Thanks @jarthana!
