[1.15.2] Idea Hot Swap Broken

[Lycanite]

Hot Swapping in IntelliJ Idea with Forge 1.15.2 does not work, it takes forever to reload, the game freezes for several seconds and then the hot swap fails.

In 1.12.2 I can hot swap with no issue and very quickly, I've also had success with hot swapping in 1.14.4 but I haven't touched 1.14.4 for a long time now. (I'm actively maintaining my mod across both 1.15.2 and 1.12.2 atm).

I setup OpenJDK8 DCEVM which does work and allows for greater changes such as function changes, etc but this is still incredibly slow compared to hot swapping with or without DCEVM in 1.12.2 which makes modding in 1.15.2 very tedious.

I don't use Eclipse so cannot test with that and my gradle config is mostly unchanged from 1.14.4 though I did recreate it from the 1.15.2 MDK download just to make sure with no difference.

I've seen similar posts with no solution but people have mentioned running without gradle, if this is possible how would I set this up in Idea?
