Thanks for the clarification, Mark.
I followed your links to get the latest of the greatest. Happy to see
all those blue circles in the build history. I downloaded:
drools-5.0.0.SNAPSHOT-eclipse-all.zip
drools-5.0.0.SNAPSHOT-guvnor.zip
Then I updated eclipse with the contents of ...eclips-all.zip,
Started eclipse and created a new runtime (which I put in my
jboss/server/default/lib folder and verified that the ones I had
installed there before were changed). I replaced the M5 version of
guvnor with the new one, and restarted everything.
That should be all I need to do, right? Been at this for a while, so
I may be having a mental lapse.
Anyways, several projects that I could build before the upgrade don't
build anymore. The build process hangs in Guvnor, as well as in Eclipse.
This is the last output I get in the server's log when trying to
compile the package I'm using for our test:
21:27:25,132 INFO [STDOUT] DEBUG 19-02 21:27:25,132
(_SelectorManager.java:<init>:27_) Loading selectors
21:27:25,195 INFO [STDOUT] DEBUG 19-02 21:27:25,195
(_ContentManager.java:<init>:45_) Loading content properties
The last thing I see in Eclipse when I try a complete clean on our
primary application is:
Building Workspace - Building all...: Invoking "Drools Builder'
on '/cbo-ejb'.
The status shows 46% complete and just hangs there.
I think it's time for a cocktail and a nice long sleep. I'll check in
tomorrow before rolling back to M5.
can you look in the error logs? I was really hoping to CR1 over the
weekend. But we need to be sure these issues are gone.
Also if it's in guvnor and eclipse it sounds like a generic problem with
drools compiler. Can I ask you to remove the plugin and try and build
the rules via the knowledgebuilder yourself, hopefully you'll find the
deadlock there yourself and be able ot print a stack trace we can
actually use. Along with the offending rules.

On the left side you see a list of red and blue circles, red
indicates that build was a failure and blue a success:
https://hudson.jboss.org/hudson/job/drools/
The last successful build has it's artifacts at:
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/
As you can see the last build was successful so now you can get all
the binaries from above.

Yes, the exception occurs on both the filesystem and Guvnor, and it happens
whether I set the value to true or false.
I found the issue and reviewed the agent code and this has been
fixed in trunk. Edson si just fixing two failing tests, but as
soon as the build turns blue again grab the latest artifact
builds and give it a try:

So from the filesystem it won't pick up changes? (does it throw the

Mark,
I have some more information for you. The exception occurs when I issue:
agent.monitorResourceChangeEvents(true|false)
If I comment out that code, I don't get the exception, but I don't get
changes either. I tried it with both the Guvnor repository and with a
deployed package on the file system.
I won't have time to create the test you requested until the weekend. Let
me
know if you still want it.

I setup a KnowledgeAgent using the example code in the JavaDoc for
KnowledgeAgentFactory to access a compiled package in Guvnor. The
package
runs fine, but changes to the package are not picked up. I believe this
is
due to the ChangeSet notification thread being interrupted. But why?
Hmm that's not good. I have the following unit test:
http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-compiler/src/test/java/org/drools/agent/KnowledgeAgentTest.java
Could you provide an update for new tests for detecting url changes?
When making the test you might find it easier to look at the previous
ruleagent tests:
http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-core/src/test/java/org/drools/agent/URLScannerTest.java

Also, I'm getting some messages about failing to read schema document.
I
think it is caused by the xml for the ChangeSet, but I'm using the
example
from the JavaDocs.
We haven't provided an XSD yet, so it'll provide schema validation
issues, those can be ignored.
Here's a snippet from the log:
