Do I have to use the Incremental Garbage collector?

[Busti]

Hello,

by default the Incremental Garbage collector (java option: -xincgc) is enabled.

Is there any particular (crashes) reason for it to be enabled or is it just for the ram performance?

Why?

I have to use the serial garbage collector for method hot-swapping to work...

I believe the reason is because it is (on average) the most performant and most widely supported.

 

Relying upon any specific Garbage Collection VM setting for your mod is a -bad idea-.  You have no guarantees that your users would have that GC type enabled.

It is just for debugging purposes. I have a Plugin that enables you to hot-swap whole classes and structural changes. Normally only method-bodies are possible.

Where did you get that plugin? I would be very interested in that plugin as it makes debugging way easier, as you can just modify it while the game is open, instead of needing to re-open Minecraft.

It is totally awesome

Since I use IntelliJ Idea I don't know if it exists for Eclipse.

Here is its download repo: (you can also search for it in IntelliJ Idea itself)

And here is a tutorial on how to use it.

Don't forget to enable the serial garbage collector for it to work. I haven't noticed any lag by using it.

Also:

Launch the game using the debugger and click the make button to hot-swap.
