Description Petr Hejl 2012-06-11 10:56:18 UTC

From time to time my ServerInstanceProviders are miisng in lookup.

1) Register Java EE server (JBoss works "well", do not use GF).
2) Close the IDE.
3) Open the IDE and expand server node.
4) There is no server.

Recently this is reproducible on my system with recent daily build in about 80% of cases.
Sometimes the server is not visible even in step 1.

Comment 1 Petr Hejl 2012-06-11 11:59:15 UTC

From the server module perspective these instances are present in lookup (my System.out starting with ==TYPE):

==TYPE org.netbeans.modules.cloud.amazon.serverplugin.AmazonJ2EEServerInstanceProvider@6c69757a
==TYPE org.netbeans.modules.glassfish.common.GlassfishInstanceProvider@4f5faa7c
==TYPE org.netbeans.modules.glassfish.common.GlassfishInstanceProvider@4f8aac0a
==TYPE org.netbeans.modules.cloud.oracle.serverplugin.OracleJ2EEServerInstanceProvider@1fca1ead

While it should something like this:
==TYPE org.netbeans.modules.cloud.amazon.serverplugin.AmazonJ2EEServerInstanceProvider@6c69757a
==TYPE org.netbeans.modules.glassfish.common.GlassfishInstanceProvider@4f5faa7c
==TYPE org.netbeans.modules.glassfish.common.GlassfishInstanceProvider@4f8aac0a
==TYPE org.netbeans.modules.cloud.oracle.serverplugin.OracleJ2EEServerInstanceProvider@1fca1ead
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@6253fe33
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@44cec792
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@35e27e8d
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@6ae1f2ba
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@71ead142
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@7b907d9e
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@589824df
==TYPE org.netbeans.modules.j2ee.deployment.impl.bridge.BridgingServerInstanceProvider@204ad408

BTW this really looks random as sometimes the content of the lookup is ok for the first time but consequent invocations return just the limited set mentioned above.
