Strange autocompletion behaviour in the xtext editor [message #780782]

Hi!

I am editing a terminal rule in my xtext file which defines a string
in quotes which may not contain braces and some other characters.

If I write

terminal SIMPLETEXT:
'"' ( !('\\' | '"' | '$' | '[' | ']' | '{' | '}') )* '"';

and hit enter, a closing curly brace is added and immediately marked as an error.

If I swap the braces in the rule:

terminal SIMPLETEXT:
'" ' (!('\\' | '"' | '$' | '[' | ']' | '}' | '{'))* '"';

this does not happen.

Digging deeper:
terminal st1:
'"' ( !('\\'|'"'|'$'|'['|']'| '{' |'}') )* '"';
adds a brace,

terminal st1:
'"' ( !('\\'|'"'|'$'|'['|']' | '{' |'}') )* '"';

does not. Do '|' bars have to be surrounded by whitespace?
Bug or feature?

With best regards
Hartmut Niemann
