Space after colon causes failure to parse tune about abc4j HOT 3 CLOSED

abc4j implements a strict version of the abc format (v1.6). This definition of 
the
format can be found here : 
http://www.norbeck.nu/abc/abcbnf.htm
In this definition , the space is not allowed between the X: and the number of 
the
tune (same for T: or any field ain general) :
field-number ::= "X:" 1*DIGIT end-of-line

I know that many tunes from the web have this blank between fields and values 
but
they don't match the v1.6 definition (maybe the v2.0 accepts it but I restrict 
the
implementation to v1.6)

You don't attach the stack trace but I think that exception occurs on your side 
at line
System.out.print("Title n°1 is " + aTune.getTitles()[0]);
because aTune is null (cannot be found when invoking int tunesNb = book.size(); 
)

So yes abc4j does not recognize it (and this is a choice because it only 
validates
strict abc grammar v1.6) but it's not a defect (unless the crash occurs in the 
abc4j
part but I don't think so)

Ah, well.  I now see in the grammar that they made a space a token, so it is 
picked
up during parsing instead of ignored.  Since that is an unfortunate side-effect 
of
how the language is written, I'll have to go the regex replacement route.  
Thanks for
looking into this.
