the following worked for me
(1) create a new xtext project
(2) use this slightly different grammar
grammar org.xtext.example.mydsl4.MyDsl with org.eclipse.xtext.common.Terminals
hidden(WS, SL_COMMENT)
import "http://www.eclipse.org/emf/2002/Ecore" as ecore
generate myDsl "http://www.xtext.org/example/mydsl4/MyDsl"
// Base elements allowed in the .wf file
Model:

(workflow=AvWFWorkflow)?
& (libs+=AvWFLib)*
);
// -----------------

"lib" name=ID ("extends" baseLib=[AvWFLib])? "{"
(

this workflow

baseName = "org.xtext.example.mydsl4"
rootPath = rootPath
runtimeTest = {
enabled = true
}
eclipsePlugin = {

}
eclipsePluginTest = {
enabled = true
}
createEclipseMetaData = true
}
code = {
encoding = "UTF-8"
fileHeader = "/*\n * generated by Xtext \${version}\n */"
}
}
language = StandardLanguage {
name = "org.xtext.example.mydsl4.MyDsl"
fileExtensions = "mydsl4"
serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
parserGenerator = {
antlrParam = "-Xconversiontimeout"
antlrParam = "5000"
options = {
memoize = true
}
}
}
}
}
i dont have any memory setting for with workflow run config a use jdk8 64 bit.
(you may have a look at / play with the following memory settings as well)
-Xmx4G -XX:-UseGCOverheadLimit
(but please file a ticket anyway)
