Aptana no longer usable on MacOS Big Sur

[uwealtmann]

Despite many tries, Aptana Studio 3 (Aptana Studio 3 Version: 3.7.2.201807300809) doesn't work any more and stops with strange errors since I updated to MacOS 11.2.3.
Tried with jdk1.8.0_231.jdk and _281 as well as adoptopenjdk-8, -11 and -14. With some, Aptana just refuses to start, others do start but you can't work.
Log looks like:
