+++ This bug was initially created as a clone of Bug #566001 +++

Use pattern matching for the instanceof operator when possible

Given:
if (object instanceof Integer) {
    Integer i = (Integer) object;
    return i.intValue();
}

When:
Clean up the code enabling "Use pattern matching for instanceof"

Then:
if (object instanceof Integer i) {
    return i.intValue();
}

Bug 566001 provides a clean up for this. It will be nice to have it as a quick assist (ctrl+1) also.

This would be an important feature to have in 4.19 M1 as instanceof pattern will become a standard feature for Java 16.
