JDev9.0.3.1038: Two problems...

Question

Hi.
I resentlly upgraded JDev9.0.3 preview with JDev9.0.3 Production Release. Well, this is not quite true. I resentlly installed Oracle Developer Suite 9.0.2, replaced JDev9.0.2 with JDev9.0.3Preview and replaced again with JDev9.0.3 Production Release. Right off I discovered two problems:
Firstly (Minor problem): Deployment of projects to simple jars. The deployer does it's job nicelly, but gets this exception:

Second: My SCM Client jar (which worked somewhat nicelly +/-) will no longer run. It's a self developet scm client using your oracle.ide.scm API. And it's not just the client which will not run, JDev as a whole freezes during initialization. The red progress bar goes all the way up to the second to last dot, and then takes a vacation. The thread dump from JDevs console looks like this:

Answer 1

Hi,
For the first problem: can you post the manifest file you're including in your JAR file? It looks like something isn't groking it properly.I have two manifest files inside the jar since you switched from a properties file type in 9.0.2 to an xml style manifest file in 9.0.3. I've included them both below:
AddinCount: 1
Addin0: novus.scm.vss.VSSClient
and
<?xml version = '1.0' encoding = 'windows-1252'?>
<extensions>
<feature>
<group name="Visual SourceSafe">
<extension>
<addin>novus.scm.vss.VSSClient</addin>
<dependency_addin>oracle.ideimpl.scm.VersionManager</dependency_addin>
</extension>
</group>
</feature>
</extensions>
For the second problem: there's no obvious reason in the WizardDefNodeRecognizer.java code why it's waiting on the AWT event thread as indicated in the stack dump you provided: this is kind of weird. If you disable BC4J (via the tools->preferences->extension manager), does the problem go away, or does it freeze at another point during startup? I'm not sure how else to investigate this without the .jar file to test.This actually solves the problem. The plugin loads and runs like a charm.
Another suggestion, which might work around the problem at least, is to defer initializing your SCM client's log page to the prepareClient() method. In fact, we (the SCM team) recommend doing this anyway (this is what we do in CVS, Clearcase and Oracle SCM), since this will prevent your client doing unnecessary initialization until the user actually activates your SCM system.I will try this. You should add this information into the javadoc, so that other developers can follow the standard you've set.
