Problem description

1. Expected behaviour: call for DatabaseMetaData#getStringFunctions returns ASCII,CHAR,CONCAT, DIFFERENCE,INSERT,LCASE,LEFT,LENGTH,LOCATE,LTRIM,REPEAT,REPLACE,RIGHT,RTRIM,SOUNDEX,SPACE,SUBSTRING,UCASE
   so there is a space between , and DIFFERENCE
   The similar thing is for DatabaseMetaData#getNumericFunctions which returns
   ABS,ACOS,ASIN,ATAN,ATAN2,CEILING,COS,COT,DEGREES,EXP, FLOOR,LOG,LOG10,MOD,PI,POWER,RADIANS,RAND,ROUND,SIGN,SIN,SQRT,TAN,TRUNCATE so there is a space between , and FLOOR
2. Actual behavior: no spaces, e.g. https://docs.oracle.com/javase/8/docs/api/java/sql/DatabaseMetaData.html#getNumericFunctions-- tells about comma-separated

Retrieves a comma-separated list of math functions available with this database. These are the Open /Open CLI math function names used in the JDBC function escape clause.
