Description of problem:

Following RHS which uses Date object comparison works fine:

DateContainer( date >= "15-Oct-2013" || date <= "01-Oct-2013" )

If there are multiple conditions connecting with "||" or "&&" as follows, syntax error occurs:

DateContainer ( (date >= "19-Dec-2015" && date <= "03-Jan-2016" ) || (date >= "17-Dec-2016" && date <= "02-Jan-2017" ))	

Exception is

===
Unable to Analyse Expression date >= "19-Dec-2015" && date <= "03-Jan-2016" || date >= "17-Dec-2016" && date <= "02-Jan-2017":
[Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String]

Additional info:
BZ-1072217 covers non-nested comparison like this:

DateContainer( date >= "15-Oct-2013" || date <= "01-Oct-2013" )

I tested with BRMS 6.1.2, and the issue still occurs.
