Google Guice usage in Errai 3.1.0/3.0.4
I pulled the dependencies in Errai 3.1 and I see that Google Guice is pulled in by errai-bus:

There are two problems with it:
A. The Errai 3.10 documentation mentions nothing about Google Guice in the dependencoes required (and btw, is probably very outdated)
B. As thoroughly discussed in the GWT community, ASM 3.1 makes for some nasty compile errors with GWT 2.7.0, which requires ASM 5:
[ERROR] Unexpected internal compiler error
java.lang.IncompatibleClassChangeError: class com.google.gwt.dev.javac.asm.CollectMethodData has interface org.objectweb.asm.MethodVisitor as super class
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:760)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
Since Google Guice is not listed as required by Errai 3.1.0, I removed it to arrive at this compile error:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Ok, so with no way around Google Guice, I decided to do something nasty - replace the ASM underneath it, with the one that GWT 2.7.0 brings in. This compiles my project, but when I run it, I get a nullMethod() exception as in:
...

(new com_peruncs_s4g_web_gwt_client_local_S4GWebApp_S4GWebApp__V).nullMethod();
}
I checked a few links and it points to Google Guice issues ... so can someone from Errai help with explaining the Google Guice relationship with Errai. Thanks.
