Description of problem: In LHS part of a rule I invoke a function that adds a number of seconds to a date (attribute of the fact), and returns the new date. Function: function Date addSeconds(Date initialDate, int numSecs) { Calendar cal = Calendar.getInstance(); cal.setTime(initialDate); cal.add(Calendar.SECOND, numSecs); return cal.getTime(); } Rule: import GeoTruckCepData; import java.util.Date; import java.util.Calendar; when $a : GeoTruckCepData( $newDate : addSeconds(date1, 40) > date2); then //do something This rule is invoked in a loop, and works correctly for a while. But after some executions, the following exception is raised: Exception in thread "Thread-1" java.lang.NoClassDefFoundError: com/petrobras/bpms/AddSeconds at

Create rule that uses a function in LHS 2. Execute the rule in a loop 3. Wait until exception is raised (in my case, usually after 20 executions) Actual results: java.lang.NoClassDefFoundError exception raised Expected results: No exceptions raised. Additional info: This problem does not occur in BRMS version 5.3.1 The error is not associated with the fact attribute type (java.util.Date). I created another function that returns the sum of two integers, and the same behavior is verified.
