[JBoss JIRA] (DROOLS-731) In a catch22 using a NOT constraint in rules shared by multiple facts
by Bill Tuminaro (JIRA)
[ https://issues.jboss.org/browse/DROOLS-731?page=com.atlassian.jira.plugin... ]
Bill Tuminaro updated DROOLS-731:
---------------------------------
Description:
I have a reproducer for these related issues.
We have encountered a couple of issues (Exceptions) when using a NOT constraint in rules that have facts associated with them when we call upgradeToVersion() or kSession.delete(). The catch22 is that one version of the NOT constraint avoids one Exception while causing another. Reproducing the issue requires 2 rules sharing the same NOT constraint. I have narrowed the issue(s) down to 2 very simple rules that use the org.drools.compiler.FactA class.
Here are the 2 rules used:
static final String ruleDrl = "package org.some.test\n" +
"import org.drools.compiler.FactA\n" +
"declare FactA\n" +
"@role(event)" +
"end\n" +
"rule \"R200_0\" when\n" +
" $FactA : FactA ($FactA_field2 : field2 == 111002)\n" +
" not FactA($FactA_field2 == 111002, this after $FactA)\n" + // version A: using this version causes a NPE when calling ksession.delete()
// " not FactA(field2 == 111002, this after $FactA)\n" + // Version B: using this version causes the IllegalArgumentException: Cannot remove a sink,
// when the list of sinks is null on the updateToVersion() call
"then\n" +
"end\n";
static final String ruleDrl2 = "package org.some.test\n" +
"import org.drools.compiler.FactA\n" +
"declare FactA\n" +
"@role(event)" +
"end\n" +
"rule \"R1437_0\" when\n" +
" $FactA : FactA ($FactA_field2 : field2 == 105742)\n" +
" not FactA($FactA_field2 == 105742, this after $FactA)\n" + // version A:
// " not FactA(field2 == 105742, this after $FactA)\n" + // Version B:
"then\n" +
"end\n";
We are hitting the following NPE using the reproducer code attached when we use the NOT Constraint labeled as 'Version A' in the rule:

[JBoss JIRA] (DROOLS-731) In a catch22 using a NOT constraint in rules shared by multiple facts
by Bill Tuminaro (JIRA)
[ https://issues.jboss.org/browse/DROOLS-731?page=com.atlassian.jira.plugin... ]
Bill Tuminaro updated DROOLS-731:
---------------------------------
Description:
I have a reproducer for these related issues.
We have encountered a couple of issues (Exceptions) when using a NOT constraint in rules that have facts associated with them when we call upgradeToVersion() or kSession.delete(). The catch22 is that one version of the NOT constraint avoids one Exception while causing another. Reproducing the issue requires 2 rules sharing the same NOT constraint. I have narrowed the issue(s) down to 2 very simple rules that use the org.drools.compiler.FactA class.
Here are the 2 rules used:
static final String ruleDrl = "package org.some.test\n" +
"import org.drools.compiler.FactA\n" +
"declare FactA\n" +
"@role(event)" +
"end\n" +
"rule \"R200_0\" when\n" +
" $FactA : FactA ($FactA_field2 : field2 == 111002)\n" +
" not FactA($FactA_field2 == 111002, this after $FactA)\n" + // version A: using this version causes a NPE when calling ksession.delete()
// " not FactA(field2 == 111002, this after $FactA)\n" + // Version B: using this version causes the IllegalArgumentException: Cannot remove a sink,
// when the list of sinks is null on the updateToVersion() call
"then\n" +
"end\n";
static final String ruleDrl2 = "package org.some.test\n" +
"import org.drools.compiler.FactA\n" +
"declare FactA\n" +
"@role(event)" +
"end\n" +
"rule \"R1437_0\" when\n" +
" $FactA : FactA ($FactA_field2 : field2 == 105742)\n" +
" not FactA($FactA_field2 == 105742, this after $FactA)\n" + // version A:
// " not FactA(field2 == 105742, this after $FactA)\n" + // Version B:
"then\n" +
"end\n";
We are hitting the following NPE using the reproducer code attached when we use the NOT Constraint labeled as 'Version A' in the rule:

[JBoss JIRA] (WFCORE-554) Unintuitive CLI behavior with 'rbac' enabled and no security-realm configured on mangement interface

Git Pull Request: https://github.com/wildfly/wildfly-core/pull/531 (was: https://github.com/wildfly/wildfly-core/pull/528)
> Unintuitive CLI behavior with 'rbac' enabled and no security-realm configured on mangement interface

> Key: WFCORE-554
> URL: https://issues.jboss.org/browse/WFCORE-554

> Components: CLI
> Reporter: Brian Stansberry

> See WFCORE-272 for background; this issue is to track the CLI part of my comment of 2014/01/28.
> With no security realm configured on the management interface and the 'rbac' provider chosen, CLI behavior is not very intuitive. You can connect and you get the [standalone@localhost:9990 /] prompt. But if you attempt to do anything that requires server-side work you get various errors indicating you aren't authorized.
> E.g.:
> {code}
> $ bin/jboss-cli.sh -c
> [standalone@localhost:9990 /] ls
> Failed to fetch the list of children: {
> "outcome" => "failed",
> "failure-description" => "WFLYCTL0313: Unauthorized to execute operation 'composite' for resource '[]' -- \"WFLYCTL0332: Permission denied\"",
> "rolled-back" => true
> }
> {code}
> In this situation the user is not going to have permissions to do much of anything at all, so it would be good to detect that somehow and respond accordingly. (The lack of a security realm means there is no way to map the user to a role. They can log in but they are not in any role and thus have no permissions.)

Version 4.4.1 of org.eclipse.jdt.core.compiler:ecj fixes this for us too. We are using Drools 5.0.1 and Jdk1.8u31.

[JBoss JIRA] (DROOLS-329) ClassFormatException when compile template with latest JDK8 (b114)
by Joel Njanga (JIRA)
[ https://issues.jboss.org/browse/DROOLS-329?page=com.atlassian.jira.plugin... ]
Joel Njanga commented on DROOLS-329:
------------------------------------
Version 4.4.1 of org.eclipse.jdt.core.compiler:ecj works fixes this for us too. We are using Drools 5.0.1 and Jdk1.8u31.
However, we can't wait until this ticket is officially resolved.
Thanks.

I have a reproducer for these related issues.
We have encountered a couple of issues (Exceptions) when using a NOT constraint in rules that have facts associated with them when we call upgradeToVersion() or kSession.delete(). The catch22 is that one version of the NOT constraint avoids one Exception while causing another. Reproducing the issue requires 2 rules sharing the same NOT constraint. I have narrowed the issue(s) down to 2 very simple rules that use the org.drools.compiler.FactA class.
Here are the 2 rules used:
static final String ruleDrl = "package org.some.test\n" +
"import org.drools.compiler.FactA\n" +
"declare FactA\n" +
"@role(event)" +
"end\n" +
