Let me just state, I haven't seriously played Minecraft since 1.12 days, played a little with a 1.16 pack but that was it. So I was poking at the FTB Overwolf app and noticed a Direwolf 20 1.19 pack. So I installed it, tried to run it, ran into an error and I can't figure out the problem. It pops up with a "Could not create Java Virtual Machine " and the log screen shows, on the last line, Unrecognized VM option 'UseConcMarkSweepGC . I check my Settings -> Instances -> Custom Arguments and it's set to

Don't even ask me what even half of that does. I dug it off of some Minecraft forum back during the 1.12 days and I have * no * idea what most of that does, it just worked. So I load up the Minecraft app itself and check it's settings, no Custom Arguments anywhere in it's settings so I have * no * idea where it's getting that UseConcMarkSweepGC.

 

Logs, logs, logs, logs, let me see...

 

Well, don't see a way to attach a new file. It's gonna be short anyway. It's one line, literally.

Unrecognized VM option 'UseConcMarkSweepGC'

 

If ya need anything else, feel free to ask, I'll try to provide it.

You can use a different garbage collector option that is compatible with Java 15, such as -XX:+UseG1GC or -XX:+UseParallelGC. You can replace the UseConcMarkSweepGC option with one of these in the jvm.options file.

A alternate garbage collector option, such as -XX:+UseG1GC or -XX:+UseParallelGC, is workable with Java 15. One of these can be used in the jvm.options file to replace the UseConcMarkSweepGC option.

You need to remove the unrecognized VM option 'UseConcMarkSweepGC' from the custom arguments. You can do this by editing the custom arguments in the FTB Overwolf app or by deleting the custom arguments file if it exists. In addition, the elastic man game is also very lively with interesting elastic skin. I think this game will definitely be a great game for you to experience.
