Should I Learn Java in 2018

I'm really excited for WASM, it should be nearly as fast as native code. Java and native code aren't far apart though, so I would say 1.5-2x faster generally

Ok, but I'm worried about the garbage collector, and if it can run concurrently without interrupting the program (as a native JVM would do it).

It should be able to... Hopefully Go and Java will be some of the first GC languages to target WASM, and we'll find out :) . Personally I'm more worried about the size of the GC getting added to the binaries than how fast it is.

AssemblyScript already does it, if I am not mistaken.

If the Javascript garbage collecter can do it then I don't see why not.

The JS GC can run in native code, in a separate native thread with shared memory access, and it can use things like memory barrier instructions, which have no equivalent in WASM yet.
