Number of Tasks returned by remote TaskService is limited to 10

Following call

List<TaskSummary> taskList = taskService.getTasksAssignedAsPotentialOwner(username, "en-UK"); (and potentially also other getter methods) are somehow limited to 10 outputs.

This is the test I made:

GET request to http://localhost:8080/kie-wb/rest/task/query?potentialOwner=anton returns this:
http://pastebin.com/2mPNa6vA – 11 entries

Following piece of code:
List<TaskSummary> taskList = taskService.getTasksAssignedAsPotentialOwner(username, "en-UK");
logger.info("task list size:"+taskList.size());

returns this in the log:
23:50:59,513 INFO [org.fi.muni.diploma.thesis.frontend.views.TaskListView] (http-/127.0.0.1:8280-118) task list size:10
