Start with Basic entity Lang

add the following productions to common.sdf3

EndOfLine      = [\n\r] 
EndOfLine      = [\n][\r] {prefer}	
DelimitedString = "q\"" Delimiter EndOfLine ~[\"]* EndOfLine MatchingDelimiter "\""
Delimiter = ID
MatchingDelimiter = ID

change
NewLineEOF = [\n\r]
to
NewLineEOF = EndOfLine

add the following production to entity.sdf3

Definition.eString = <
	eString <ID> = <DelimitedString>
>

Save and build the project

Add the following test to test-example.spt

test Delimited Strings [[

	eString twentysix = q"EOS
This
is a multi-line
heredoc string
 EOS"
]] fail

There is a space in front of EOS which should cause it to fail.

On saving the test file is marked at the head with the following error.

Internal parsing error: java.lang.NullPointerException (recovery failed)

If the fail suffix is removed the test fails with a parse failure but the NPE is not triggered.

The following Exceptions where logged in the Error Log.
