[rules-users] pattern

[Markus Helbig]

Drools Documentation says:

Matches a field against any valid Java Regular Expression. Typically
that regexp is a String, but variables that resolve to a valid regexp
are also allowed. It is important to note that different from java, if
you write a String regexp directly on the source file, you don't need
to escape '\'. Example:

but

"Test\s+" is a valid RegEx (it was valid in Drools 3.x too), but now:

SyntaxfehlerRule Compilation error : [Rule name=OnlineStreaming Start,
agendaGroup=MAIN, salience=100, no-loop=true]
com/p7s1/swi/phoenix/n24/Rule_OnlineStreaming_Start_0.java (19:923) :
Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ )



What i'm doing wrong here?
