Inline
Test I

After testing Undo/Redo I noticed that it didn't work well so I closed the file From.java and tried to test ClassA again. 
When I put the caret into from.m1()(true, 5) and selected Refactor > Inline.. this exception has been thrown.

Sorry, could you please provide more details ? The link to the test is broken, but I managed to find some code like:

public class ClassA {

    int num = 5;

    public void m() {       
        From from = new From();
        from.m1(true, 5, "abcd");
        from.m2();
        from.m3();
        
    }

...
but inlining from.m1() worked OK.

Thanks.
