Seems like an exception is thrown while Engine.parseBlockStatements() is trying to find the right method for the selection:

Also an exception is thrown during the selection itself. The method in the loop is:
private void completionOnMessageSend(ASTNode astNode, Binding qualifiedBinding, Scope scope) {
}
And the exception is:
java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 10

From what I can tell this is the line that causes the problem:

After this change the selection works as expected.

If I remove SelectionParser.consumeInstanceOfExpression(), which was added for https://bugs.eclipse.org/bugs/show_bug.cgi?id=577508, the bug is gone. Oddly, Stephan reported the bug against 4.21 and supposedly the change was done for 4.22+...
Maybe some earlier attempts at supporting pattern instanceof caused the problem already in 4.21.

Just another manifestation of same issue from #853 :
import java.util.concurrent.CompletableFuture;
public class F3NotWorking {
public CompletableFuture<String> readOutStream() {
return CompletableFuture.supplyAsync(() -> { // <-- F3 to open supplyAsync() declaration doesn't work
try {
return "";
} catch (Throwable e) {
String message = "";
if (e instanceof Exception) { // replace with message == "" and F3 will work again
message = "This instanceof breaks F3 above!!!";
}
throw new RuntimeException(message, e);
}
});
}
}
