Unable remove a rule package when it was added after it has been added and removed.
I have seen the issue [#JBRULES-358]. My test go a little far than [#JBRULES-358].
I remove the package again when it was added for the seconn time, then an exception was
thrown.
My test case is:
public void testRuleBaseRemove() throws Exception
{
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
File file = new File("test.drl");
//add and remove
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(new FileReader(file));
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
ruleBase.removePackage(pkg.getName());
//add and remove again
builder = new PackageBuilder();
builder.addPackageFromDrl(new FileReader(file));
pkg = builder.getPackage();
ruleBase.addPackage(pkg);
ruleBase.removePackage(pkg.getName());
}
the exception is throw:
