I ran into a case that BOBYQAOptimizer hang in line 485. trsbox is

final double[] dsqCrvmin = trsbox(delta, gnew, xbdi, s,
hs, hred);
Here is the test case for it. After reducing the value to <2.24 it
hang in
trsbox method without progress.
Can someone shed light on what might be happening, and how to deal
with
it? Thanks.
The short story is that BOBYQAOptimzer is not really supported.
The long story is on the bug-tracking system:
