We patch things, they patch things too. You know the drill, we need logs.

Enjoy though

Seems like their ASM is erroring out... pinging @sfPlayer1

[sfPlayer1]

Hmm interesting. What is ForgeEssentials editing in EntityPlayerMP? The error means that the fc injector found 3 location matches instead of the expected 1.

I also need the CLASSLOADER_TEMP/net/minecraft/entity/player/EntityPlayerMP.class from the same setup without FastCraft installed. The server needs the additional parameters -Dlegacy.debugClassLoading=true -Dlegacy.debugClassLoadingSave=true to generate said file. Don't forget to disable it again afterwards.

im generating same error on my FTB Infinity server, here is the file you are requesting. https://drive.google.com/open?id=0B47wGOooeWGIV0pQZTZoQkxmZDA&authuser=0

[sfPlayer1]

The file isn't publicly accessible.

[FiveEYZ]

should be public now

The real issue is in the mixin library ForgeEssentials pulls in.

There's an extra transformer invocation in:
at org.spongepowered.asm.mixin.transformer.TreeInfo.applyTransformers(TreeInfo.java:147)

Apparently it also causes LaunchClassLoader to drop the class, loading it again later, which whould be the 3rd invocation Fastcraft counted.

That's invalid since the class loader prevents multiple invocations. Doing so regardless imposes extra requirements on the IClassTransformer implementations, which aren't necessarily met.

Same bug experienced on custom RR Server log is below no crash report

You can potentially work around it by specifying the extra java parameter -Dfastcraft.asm.permissive (before -jar).

Seems to be working so far thanks I imagine it is pretty dirty to bypass it

[P3rf3ctXZer0]

Confirmed fix :D I don't know what you mean by dirty but I am not losing any frames for the bypass :D

[FiveEYZ]

think he meant "dirty to bypass it" because its a server issue and not client.

[P3rf3ctXZer0]

Fixed
