hi all,
the exception below is usually thrown when the system is busy(usually 9-10
am everyday);
The rules runs perfectly when unit test or any other time when the system
is not very busy(like 22:00 - 4:00 every day);
Our system processes 13000000 pieces of data each day, with
4-5 java.lang.ArrayIndexOutOfBoundsException thrown on average.It's not
very often but doubtful.
The logs are shown below:

Caused by: java.lang.ArrayIndexOutOfBoundsException
I looks like there's some issue in mvel2's parser.The problem occurs when
dynamic compiling mvel2 code.
And every ArrayIndexOutOfBoundsException is thrown around here:
'Helper.containsAny(offerSubject, ((Set)colMap.get("_set_212")))' .This
is
a custom static function call which implements come sort of operation not
supported by drools5.
Is this a bug about mvel2?Or any one encountered this problem also? How
could I avoid it?
Thnaks!

I am no drools expert but I am working a few mvel bugs in free time. I
am still sorting through the code.
I will try to work in test case but I don't know where
the line
Helper.containsAny(offerSubject, ((Set)colMap.get("_set_212"))) is
coming from.
This isn't in one of your rules is it?
The index out of bounds is from the mvel code.
Pretty sure one of the project maintainers will give us more to go with.

Anyway to get a scrubbed rule ? I will throw it through a debug
instance. Also what jdk/jre are you running on?

Sorrry for the latency of my reply...
I was surrounded by other things these days~
So, there are many rules in our system(about hundreds of them). Most of the
time, the "not very busy" time period, this problem does not occur.
And when the problem occurs, I discovered that it is always the line:
Helper.containsAny(offerSubject, ((Set)colMap.get("_set_54")))
or:
Helper.containsAny(offerPublishIpArea, ((Set)colMap.get("_set_54")))
where the exceptions were thrown.As my original post shows.
The "Helper" class is a handful of static functions, which returns boolean
results, to extend some special predicate which is not supported by drools5
now.
The 'containsAny' method, for example, it checks if the first argument(a
string) contains any one of strings in the set passed in as the second
argument.
The real drl file was here:
package com.alibaba.china.ruleservice.dsl.binding.drools5;
import com.alibaba.china.avatar.offer.rulematch.facts.OfferEntity;
import com.alibaba.china.avatar.offer.rulematch.facts.EventContext;
import com.alibaba.china.avatar.offer.rulematch.facts.MemberInfo;
import java.util.Set;
import java.util.HashSet;
import java.util.Map;
import java.util.HashMap;
import java.util.Collection;
import java.util.Date;
import java.math.BigDecimal;
import java.math.BigInteger;
import java.math.RoundingMode;
import com.alibaba.china.ruleservice.dsl.binding.drools5.CustomOpInvoker;
import
com.alibaba.china.ruleservice.dsl.binding.drools5.CustomActionOpInvoker;
import com.alibaba.china.ruleservice.dsl.binding.drools5.translate.Helper;
import com.alibaba.china.ruleservice.dsl.binding.drools5.InferenceCounter;
global java.util.Map colMap;
global java.util.Map dateMap;
global com.alibaba.china.ruleservice.dsl.binding.drools5.CustomOpInvoker
customOpInvoker;
global
com.alibaba.china.ruleservice.dsl.binding.drools5.CustomActionOpInvoker
caoInvoker;
global com.alibaba.china.ruleservice.dsl.binding.drools5.InferenceCounter
inferenceCounter;
rule "23110"
when
mf2:MemberInfo(memberType == "free")
mf1:EventContext(Helper.containsAny(offerPublishIpArea,
((Set)colMap.get("_set_1"))))
mf0:OfferEntity(Helper.containsAny(offerSubject,
((Set)colMap.get("_set_0"))) && Helper.strContains(offerCategory,
"usb") &&
offerUnitPrice < 16.88)
then
end
this file contains hundreds of rules, but I only shows you the one which
caused the problem(a.k.a where the ArrayIndexOutOfBoundsException thrown..);
I suspect that there are some thread safety issues in the mvel2 compiler,
because the problem is not shown every time it runs, it is likely to shown
up in some 'very busy' time-period.
