Hi
Can you show us the Java code of the tJava_3? it will be helpful for us to locate the problem.

This is the code
/**
* stop
*/
NB_ITERATE_tJava_3++;
/**
* start
*/
ok_Hash.put("tJava_3", false);
start_Hash.put("tJava_3", System.currentTimeMillis());
currentComponent = "tJava_3";
int tos_count_tJava_3 = 0;
/**
* stop
*/
/**
* start
*/
currentComponent = "tJava_3";
tos_count_tJava_3++;
/**
* stop
*/
/**
* start
*/
currentComponent = "tJava_3";
ok_Hash.put("tJava_3", true);
end_Hash.put("tJava_3", System.currentTimeMillis());
if (!globalMap.get("current_year").equals(
String.valueOf((Integer) globalMap
.get("tLoop_4_CURRENT_VALUE")))) {
tSetGlobalVar_1Process(globalMap);
}
if (context.getProperty("current_year").equals(
String.valueOf((Integer) globalMap
.get("tLoop_4_CURRENT_VALUE")))) {
tRunJob_1Process(globalMap);
}
/**
* stop
*/

context.getProperty("current_year").equals(
String.valueOf((Integer) globalMap
.get("tLoop_4_CURRENT_VALUE")))

The problem is caused by this code, it returns a null value, modify it to the below code will work, because you use a global var to store the value on tJava_4.

((String)globalMap.get("current_year")).equals(
                                String.valueOf((Integer) globalMap
                                        .get("tLoop_4_CURRENT_VALUE")))
