Because the cache is synchronized, the one-time-initialize object would be added under the lock and then the lock released before the object is populated and returned as a cached credential, allowing atomic action with a minimum of contention.
> For each cached entity, a NamingListener could be established which would invalidate (or possibly update) the cached value as the database changes.
> Alternatively, a NamingListener could be established for all identities, and each update would invalidate or update any cached values corresponding to the DN or resolved name.
> This is a complex design topic so discussion is welcome.

[JBoss JIRA] (DROOLS-1243) ClassCastException at runtime when trying to match "from" and a built-in accumulate function.
by Matteo Mortari (JIRA)
Matteo Mortari created DROOLS-1243:
--------------------------------------
Summary: ClassCastException at runtime when trying to match "from" and a built-in accumulate function.
Key: DROOLS-1243
URL: https://issues.jboss.org/browse/DROOLS-1243
Project: Drools
Issue Type: Bug
Components: core engine
Reporter: Matteo Mortari
Assignee: Mario Fusco
Priority: Minor
A rule like this
{code:java}
global java.util.List list;
rule R when
$theFrom : Double() from accumulate(MyPerson( $val : age );
sum( $val ) )
then
list.add($theFrom);
end
{code}
works fine but if modified like:
{code:java}
import java.math.BigDecimal;
global java.util.List list;
rule R when
$theFrom : BigDecimal() from accumulate(MyPerson( $val : age );
sum( $val ) )
then
list.add($theFrom);
end
{code}
then it breaks at runtime, with {{ClassCastException}}.
Suggested correct behavior:
{quote}it should either raise a compilation error (if it is a typed function, like sum()) or just fail to match at runtime, as BigDecimal() does not match the result of sum(){quote}
full stack trace for reference:
{code:java}
