Sets the jar filter for the executor.
This filter can contain any name of a jar file that should be considered during search.
If not set, no filter is applied. If the argument is null, no filter is used. Otherwise, all
strings in the argument are used as jar files and only those jar files will be used in a search.
Using filters can speed up the search process.
Filters can be set any time, a new filter will overwrite an existing one (using null will disable filtering).
@param filter new array of jar file names for filters, null means do not use any filter.
