[~smarlow] is that published as a SNAPSHOT? And yes, the master branch of hibernate-orm upstream is JDK 9 compliant outside of some library (like Javassist) issues with Java 9.

[~thchuong] could you also try the [https://github.com/jboss-javassist/javassist/commits/test/java9-jigsaw] branch. It should build with Apache Maven 3.3.9 (via "mvn clean install", which should give you a local "3.21.0" build).

[JBoss JIRA] (DROOLS-1245) Document limitation of (legacy) Accumulate CE Alternate Syntax: single function with return type
by Matteo Mortari (JIRA)
Matteo Mortari created DROOLS-1245:
--------------------------------------
Summary: Document limitation of (legacy) Accumulate CE Alternate Syntax: single function with return type
Key: DROOLS-1245
URL: https://issues.jboss.org/browse/DROOLS-1245
Project: Drools
Issue Type: Enhancement
Components: docs
Affects Versions: 6.4.0.Final
Reporter: Matteo Mortari
Assignee: Matteo Mortari
Document limitations and common pitfalls:
h2. from+accumulate does not iterate
This does NOT iterate over the elements of the accumulate function:
{code:java}
rule R when
$theFrom : Object() from accumulate(MyPerson( $val : name );
collectList( $val ) )
then
list.add($theFrom);
end
{code}
and in fact the binded $theFrom : Object() is the List returned by the collect list.
While normally the "from" iterates over the element of list/iterable collections.
{code:java}
rule R1 when
$list : List( )
$s : Integer() from $list
then
out.add($s);
end
{code}
h2. limited scope of compile-time checks
Compile-time checks are performed for Accumulate Functions returning a single result.
Compile-time checks are NOT performed for iterable Accumulate Functions, the case when the accumulate function returns a collection.
With ref to DROOLS-1243.
For instance this fails at compilation:
{code:java}
rule R when
$theFrom : BigDecimal() from accumulate(MyPerson( $val : age );
sum( $val ) )
then
list.add($theFrom);
end
{code}
but the following does passes compilation:
{code:java}
rule R when
$theFrom : String() from accumulate(MyPerson( $val : name );
collectList( $val ) )
then
list.add($theFrom);
end
{code}
only to fail later at runtime with CCE:
{code:java}
Caused by: java.lang.ClassCastException: java.util.Collections$UnmodifiableRandomAccessList cannot be cast to java.lang.String
{code}

[JBoss JIRA] (ELY-462) DirContext suppliing service to be used in LDAP realm
by Jan Kalina (JIRA)
[ https://issues.jboss.org/browse/ELY-462?page=com.atlassian.jira.plugin.sy... ]
Jan Kalina updated ELY-462:
---------------------------
Description:
There will be DirContext suppling service, which will be referenced by LDAP realm:
* output of service will be ExceptionSupplier<DirContext>, but the returning DirContext will be only delegator, which will call real DirContext and instead of close() it will do returnContext()
Problematic place: DirectEvidenceVerifier
* context can be copied using (Context)ctx.lookup("")
* probably "we can take a DirContext obtain the environment settings from it and just place in the name and credential being tested and create a new contex - if that is possible we can eliminate needing our own factory interface if possible "
