Consider the following KB:

rule "Dummy timer rule 1"
timer (cron: 0 0 0 * * ?)
when
	Integer()
then
	insert("Dummy timer rule 1");
	System.out.println("Dummy timer rule 1");
end

rule "Dummy timer rule 2"
timer (cron: 0 0 0 * * ?)
when
	Integer()
then
	insert("Dummy timer rule 2");
	System.out.println("Dummy timer rule 2");
end

Then consider the following steps:

1. insert new Integer
2. advance clock by +1 day

Expected result: 3 facts in the working memory, the original Integer, and two String.

Actual results: 2 facts in the working memory, the original Integer, and only 1 String, from the former of the two rules.

I hope this is not another duplicate report, I've done search on Jira before submitting, but kindly excuse me if I didn't found an already open bug which is a greater case of this one =)

I will attach relevant source code to replicate the issue, and related material
