Adding a comment breaks parsing of a Shex file

[tonicebrian]

Whenever I add a comment to a shape, the Shex fails to compile. For instance, this shape breaks the whole parsing:

:MyShape {
  obo:RO_0000081 IRI ; # Comment
}

with error:

line 1:1552 missing '}' at '<EOF>'
[info] - should validate against the Shex definition *** FAILED ***
[info]   Error at 1:1552 missing '}' at '<EOF>' (RDF4JMarshallerSpec.scala:88)

while

:MyShape {
  obo:RO_0000081 IRI ; 
}

compiles and works perfectly. It seems like the comment is commenting out the rest of the file till the end.

Could it be something related to the warning you can see when generating the code from the ANTLR file?
