OpenJFX custom build - Java application crash (semi-related to 8262276)

Mon Mar 15 12:38:16 UTC 2021

I've tried to remove this particular assert statement at "JSCast.h:143":
// ASSERT_UNUSED(vm, canCast == from->JSCell::inherits(vm, Target::info()));

... and now application crashes at different assert statement:

Is there any way we could turn off assertions in general when producing
debug build?
