[CDO] Startup error on linux getConfig().getBufferProvider() == null [message #1712853]

Hi,
I am trying to get some tests running which start an embedded cdo server with DBStore and H2 database. The tests are started by the maven\tycho build process.

The build runs without any problem on windows. But I encounter the following problem when running it from a Jenkins installed on Linux:

[INFO] Repository configuration manager extension started
[INFO] Net4j extension starting
[INFO] Net4j acceptor starting: tcp://0.0.0.0:2036
[ERROR] getConfig().getBufferProvider() == null
java.lang.IllegalStateException: getConfig().getBufferProvider() == null
	at org.eclipse.spi.net4j.Acceptor.doBeforeActivate(Acceptor.java:155)
	at org.eclipse.net4j.internal.tcp.TCPAcceptor.doBeforeActivate(TCPAcceptor.java:225)
	at org.eclipse.net4j.util.lifecycle.Lifecycle.internalActivate(Lifecycle.java:73)
	at org.eclipse.net4j.util.lifecycle.ShareableLifecycle.internalActivate(ShareableLifecycle.java:43)
	at org.eclipse.net4j.util.lifecycle.Lifecycle.activate(Lifecycle.java:162)
	at org.eclipse.net4j.TransportConfigurator.configureAcceptor(TransportConfigurator.java:108)
	at org.eclipse.net4j.TransportConfigurator.configure(TransportConfigurator.java:78)
	at org.eclipse.emf.cdo.server.internal.net4j.bundle.Net4jAppExtension.start(Net4jAppExtension.java:38)

I am a little stuck and do not know where to look. Any help would be appreciated.

Regards,
Thorsten

Hi Thorsten,

I have no idea why it would behave differently on Linux. If you enable tracing (see
https://wiki.eclipse.org/FAQ_for_CDO_and_Net4j#How_can_I_enable_tracing.3F ) do you get more hints on the problem?

Cheers

Seems to have been a configuration issue. The test is run as a plugin unit test and the launch config is derived from the dependencies. Meanwhile the server gets started by the test.
Thanks for the answer anyways.

For me this was the solution:

Net4jUtil.prepareContainer(container);

Net4jUtil.prepareContainer() is only useful if you run stand-alone (no extension registry available) or use a custom container (not IPluginContainer.INSTANCE).

When you use IPluginContainer.INSTANCE the extension registry automatically populates the container with the needed factory from the plugin.xml:

<factory
class="org.eclipse.internal.net4j.buffer.BufferPoolFactory"
productGroup="org.eclipse.net4j.bufferProviders"
type="default"/>
