Nevermind, was confused about versions. The RegistryEvents are added in 1.11, so just use preInit to register your blocks.

No, I have not... *facepalm* Where should I call upon that? PreInit? Yes. Or better, you should use the new RegistryEvent.

I can not find where you call the ModBlocks.registerBlocks method. Do you actually call that?

Did you register your TileEntity ?

Where do you actually register your Blocks?

Follow this: http://mcforge.readthedocs.io/en/latest/gettingstarted/. The "advanced" way is just more hassle than needed, and is a remnant of modding before Gradle was used to set up your workspace.

It's weird, as I don't get the message, and I only have Java 8 installed. Did you try updating your Java to the latest version?

Allocate more RAM to Minecraft.

What installer are you using? Just installer or installer-win ? Also, for which Minecraft and Forge version?

You can still download Java 6 from the Java archives. But it shouldn't complain about you using a newer version of Java. Can you post the error log?

How did you setup your workspace?

You need to add the inventory variant to your blockstate JSON or make an Item model JSON for your blocks.

Just like with everything related to programming: you learn it by doing it. Some blocks in Minecraft are composed of multiple things. Take for example the furnace: it is a Block , it has a TileEntity , it has a Container and a Gui . The Block can be rotated in 4 directions and has an on/off state. So start for example with making a faster furnace. That will cover a lot of stuff for you. Now I'm not saying the furnace does it in the best way possible, as it isn't. It uses 2 Blocks while the on/off state could be stored in metadata. So try to mimic something from vanilla, and then change it. If you have issues, make a thread on the forum and we will help if we can.

Yes. You can always just try it yourself to figure it out.

JVM Flags: 3 total; -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx4G -Xmx256M You still have 2 -Xmx flags. It will only use the latest one, so 256MB. If this isn't visible on the launcher, try looking for the JAVA_OPTIONS environment variable where it might be set. If so, remove the environment variable.

Where do you register each IItemColor ? You have to register them before Minecraft can use them.

Standard Expansion is crashing, remove/update the mod and report it to the author.

It is in your run directory, then in config/splash.properties .

Call setHasSubtypes(true); from your Item constructor.

Go into your file explorer and see if that path exists (note: testmod: is equivilent to assets/testmod/). And it is case sensitive. Your JSON is call Testitem.json, and it's looking for testitem.json. Make the file all lower case.
