Found FMLCorePluginContainsFMLMod marker in OpenModsLib-1.7.10-0.10.1.jar. This is not recommended, @Mods should be in a separate jar from the coremod.

Really old versions of Minecraft/Forge are no longer supported.

Please update to a modern (1.14.4/1.15.2) version to receive support.

 

More information on supported versions can be found in the LTS link at the top of every page.
