Codename One Animation Trouble (also in Solitaire demo)?

Question

What happened to the Codename One animation? I use a lot of them, and since December, my application no longer works. When I left in June, everything was fine (and it has been like this for more than a year).

My application is a game with checkers (checkers) and has been available in application stores since 2013. After watching the CN1 Poker demo, I completely rewrote my GUI because I wanted to add such animations to my application. Now what happens is that I suddenly get an index from related exceptions. I narrowed it down to the following situation:

cont.addComponent(comp);
...
...
cont.getComponent(0);  <-- index out of bound exception: 0 out of 0

I already used newVM = true in June, which, in my opinion, became the default. I tried to fix the situation by adding

cont.animateLayoutAndWait(100);

after calling addComponent. This fixed the index from the associated exceptions, but now the application just crashes at random times after it works normally for a short time. I tried, but could not find the source of the problem. Something has changed in CN1, so my code no longer works. (See also the old forum, searching for “drafts,” where I posted a complete list of my main design.)
