Unexpected exit with no stack trace or other information
--------------------------------------------------------
Key: JBRULES-1060
URL: http://jira.jboss.com/jira/browse/JBRULES-1060
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.0.GA
Environment: Windows XP sp2, 1GB RAM, Sun Java JDK 1.5.0_11, Eclipse 3.3 Build

When inserting a number of facts, (seems to be somewhere around 450 facts in this test
example here), the rules system exits unexpectedly with no stack trace or other
information. I pared down my code to a simple example that demonstrates this below. I
can get it to run normally if I insert 450 facts, however 475 or above exhibits this
unexpected system exit. I am running this from Eclipse.
Garbage.java (fact bean):
package com.sample;
public class Garbage {
private char id;
private int someNumber;
public Garbage(char garbageId, int someNumber) {
setSomeNumber(someNumber);
setId(garbageId);
}
public char getId() {
return id;
}
public int getSomeNumber() {
return someNumber;
}
public void setId(char id) {
this.id = id;
}
public void setSomeNumber(int someNumber) {
this.someNumber = someNumber;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("a Garbage { ");
sb.append("someNumber= ");
sb.append(getSomeNumber());
sb.append(", id= ");
sb.append(getId());

I just ran this and got:
[ObjectInserted: handle=[fid:1260:1260:a Garbage { someNumber= 310, id= C }]; object=a
Garbage { someNumber= 310, id= C }]
java.lang.OutOfMemoryError
Which means its running out of memory, just give your JVM session access to more memory.

---------------------------------------
notice you have a nested loop:
for (int i = 1; i <= 3; i++) {
for (int j = 1; j <= 475; j++) {
so thats actually 1425 facts its attempting to insert.

----------------------------------------
yes I can run this to completion if I give it -Xmx500M (not sure what else will work, I
just tried it):
Something is up
Run time (milliseconds): 21100
Finished problem at Tue Aug 21 17:41:11 EST 2007
This is a combination explosion, but it certainly works. In my case, I didn't see an
OOME reported as well (on Linux, Fedora 7, JSE5). I will try on the mac as well, but it
seems in some cases OOME is being swallowed somehow before it is being reported. Perhaps
command line it wil show it (I was running it from within eclipse).

When inserting a number of facts, (seems to be somewhere around 450 facts in this test
example here), the rules system exits unexpectedly with no stack trace or other
information. I pared down my code to a simple example that demonstrates this below. I
can get it to run normally if I insert 450 facts, however 475 or above exhibits this
unexpected system exit. I am running this from Eclipse.
