I was able to narrow down my problem to the following case:
I'm creating Kubernetes pod with two containers:
couchbase - initialized version with one bucket from offical Couchbase 3.1 image
my java app that tries to connect to Couchbase and use this bucket
My app's code is as follows (full content of main function):
CouchbaseEnvironment ce = DefaultCouchbaseEnvironment.builder()
.connectTimeout(10000)
.build();
CouchbaseCluster cluster = CouchbaseCluster.create(ce, "127.0.0.1");
Bucket bucket = cluster.openBucket("my_user", "some_pass");
JsonObject jo = JsonObject.empty();
jo.put("SomeName", "someValue");
bucket.upsert(JsonDocument.create("my_id", jo));
It fails on last command with timeout:

I don't know how to fix this or get to the root cause as timeout is very unlikely as the Couchbase is having only one, empty bucket.
PS when configured logs for Couchbase client I was able to see keep-alive entries working just fine.
I'm using official Couchbase java client in version 2.1.0. Also tried 2.1.6 and 2.2.5 but no luck.
The problem was created by me - the bucket I have created didn't had password set and I tried to connect to it with password...
I wanted to delete whole answer but I thought that it might be helpful in case someone else have similar problem

With the release of Apache TomEE Plus 7.1.2, our application is not starting. It starts in 7.1.1. I narrowed it down to this code change in org.apache.openejb.assembler.classic.Assembler.createApplication method at line 829. It seems to only happen when there are multiple web modules defined in the application.xml. I can't find any doc on why this was introduced.
for (Map.Entry entry : appContext.getProperties().entrySet()) {
if (Module.class.isInstance(entry.getValue())) {
appContext.getProperties().remove(entry.getKey());
}
}
One thing to note is if I put the 7.1.1 version of the openejb-core jar, the error goes away. Here is the stacktrace.

Any suggestions?
It looks like you do not have permission to access the PostgreSQL database.
Did you edit pg_hba.conf?
I made a video on installing OpenNMS that you might find helpful. It covers the changes you need to make to PostgreSQL so that OpenNMS can access it.

The Partial heap won't load with visualvm.
What could cause this?
Is this a known bug?
Is there a workaround?
This is a known bug and has been fixed starting with Java 8 Update 60.
See https://bugs.openjdk.java.net/browse/JDK-8044416
Java 8 ticket: https://bugs.openjdk.java.net/browse/JDK-8077507

On local computer (local tomcat) it works fine. On machine I have this error. I'm confused, because I don't have any ideas why it doesn't work.
It looks like your operating system has run out of file descriptors:
java.io.IOException: Too many open files
if you are running on linux have a look at the ulimit command
I'm trying to run the java-fx sample Modena that can be found here. I use Netbeans 8.0 Beta, JDK8 last release on Windows 8. I wonder why I can't even compile it.
In fact the first exception that happens is this.
I note to be a newbie in JavaFX.
The line of exception in the program is:
private static final String testAppCssUrl = Modena.class.getResource("TestApp.css").toExternalForm();
I assert that I verified and the file existed. And the example jar file can be run on my computer with my Java default configuration which is explained above.

The problem was with running only the main file with Shift+F6. I should have used F6 to run the project instead. F6 runs the project but Shift+F6 only runs the file containing the static main method without considering the project configuration.
