I've done a little debugging. The code fails in the following segment:

 

public static class HashTableIterator

...

 while ( this.entry == null ) {
                    this.row++;
                    if ( this.row == this.length ) {
                        return null;
                    }
                    this.entry = this.table[this.row]; // ---> index out of bounds exception
                }

}
 

this.row has the same value as this.length despite the condition above it. Probably a race condition issue.

Not really :(

In your situation I tend to keep removing rules and data while still making sure the error happens, to get it down to a minimum. Please do try, as this isn't an error that should happen. Or alterntaively you can open drools-core and drools-compiler in eclipse and execuse and debug this yourself - in your situation this might best. you can put in a breakpoint to listen for that particular exception.

It's hard for me to provide a self contained project. The drl is long and uses several business objects. It's the same drl as we've been using for 306 minus the keyword changes.

Is there anything else i can check or provide you in order to solve this matter.

 

Thanks

Can you provide us a self contained project which creates this error? Unless we can recreate it, it will be very hard to track it down. Please attach the project to a jira and we'll make it a priority.

Hello,

 

I've just started integrating MR3 into my project (I've previously used 3.06). The drl compiles and everything seems fine, but during

tests the following exception is thrown for time to time:

 

java.lang.ArrayIndexOutOfBoundsException: 17

 at org.drools.jsr94.rules.StatefulRuleSessionImpl.addObject(StatefulRuleSessionImpl.java:162)

 

This only happens during high load tests.

Can anyone help me?

 

Thanks
