8191867: Module attribute in 54.0+ class file cannot contains a requires java.base with ACC_TRANSITIVE or ACC_STATIC_PHASE

[Alan Bateman]

The draft JVMS for Java SE 10 forbids an entry in the requires table of 
a Module attribute in a 54.0 or newer class file to require java.base 
with the ACC_TRANSITIVE or ACC_STATIC_PHASE modifiers. This needs an 
update to the module-info.class parser:

For now, the ModuleDescriptor.Builder API is not updated but arguably it 
should so that it retains its alignment with what is allowed and not 
allowed in the Java Language.
