The bug comes partially from eclipse, i found it in the eclipse version shipped with fedora 33 (4.16; 2020.06), it is partially corrected in eclipse 4.18M2 (2020.12, to be released in few days).

The apparent application freeze was due to a creation of modal window with a width of 0px

this is a problem of windows positioning and dimensioning.

Comment 2 jonas-miles-kwecl 2020-11-18 17:08:13 UTC
After investigation it appears that the freeze is not one but only that the modal window is created with a width of zero.

It is corrected since eclipse 2020.12 (4.18) M2
