Parsing issue in LIKE ESCAPE '\'

[anderruiz]

I'm not sure if this is a duplicate of other issues related with ESCAPE keyword, in my case this query is causing an error

SELECT * FROM t1 WHERE UPPER(t1.TIPCOR_A8) like ? ESCAPE '' ORDER BY PERFILB2||TRANSLATE(UPPER(AP1SOL10 || ' ' || AP2SOL10 || ',' || NOMSOL10), '?', 'A') asc

I get this error:

Exception in thread "main" net.sf.jsqlparser.parser.ParseException: Encountered " <S_CHAR_LITERAL> "' || AP2SOL10 || ' "" at line 1, column 112.

Looks like something related with ESCAPE keyword because the parsing works if I changed the ESCAPE from '' to '\' for example

Does it make sense?
