So I build a model of a tank in blender which I implemented later on in jmonkey with a spatial. But when I gave the model texture, materials and morde detail, jmonkey responds with an error "NullPointerExeption" and closes the test application which ended as a blackscreen before.
Is anyone familiar with this problem?

We are testing with STORAGE_WRITE_API to insert data into BigQuery. We've seen several errors/warnings in our Dataflow pipeline(written in Java). It might work well in the beginning, but eventually the system lag would be increasing, it would stop processing any data from PubSub and the unacked messages piled up.
One common warning is:

There was a production issue related to connection being stuck after streaming 10MB which has been fixed. If you try again, it should work.
Problem
I have a org.apache.tinkerpop.gremlin.structure.Vertex that I call v, and a JanusGraph instance I call graph.
I attempt to delete v with:
v.remove();
graph.traversal().tx().commit();
but I get a null pointer exception

The following line in the janusgraph-core library is where null pointer occurs:
if (multiplicity.isConstrained()) {
So it would appear that when the library is reading through all the data for the vertex in order to then delete it, it comes across an edge for which there is no multiplicity?
My question is: what might be the reason I'm unable to delete the vertex here, and what are some ideas for how I might explore this issue?
Notes
I am using Janusgraph version 0.2.0
I am using cassandra as the backend data store for the graph database
My graph contains edge labels of Simple and One-to-one types
I get a nullpointer exception also if I try and read the graphSON representation of the vertex
I'm Kind new in Cloudsim and CloudReports Extension so i don't know why
when running the CloudReports simulator it gives this Error:
nullpointerexception at org.cloudbus.cloudsim.power.powerdatacenter.processcloudletsubmit(powerdatacenter.java:269)
I was adding a cloudlet scheduling Algorithm to the Extension
All I can see that the error happens with cloudlets Migration.
I tried searching alot about how to Fix it but didn't find something that will help me.
the Error is like this:
java.lang.NullPointerException

I ran into the same problem while I was following the simulation examples provided in the CloudSim project. After debugging figured out that the problem was with setting the UserID of the created cloudlet. I was setting a random value as the userId while the simulation retrieves the cloudlet using the brokerId. So setting the userId with the brokerId that was created did the trick for me.
// dataCenterBroker is the instance of the broker which you created
int brokerId = dataCenterBroker.getId();
//setting the userId after creating the cloudlet
cloudLet.setUserId(brokerId)
We have an app in production and many of the errors from the crash reports (we use Sentry and BugSnag) are not very meaningful and hard to find/reproduce. How should we deal with them? Most of the time they look like as an internal errors in the iOS/Android (at least from the reports) and don't point to something which we have done wrong in the React Native part. Let's give you an example:
NullPointerExceptioncom.facebook.react.uimanager.NativeViewHierarchyManager in dropView - Attempt to invoke virtual method 'int android.view.View.getId()' on a null object reference.
The raw output of this error is:

This started to become very annoying because of the time spent on them without any useful results.
I am in the process of migrating an application from WAS 7 to WAS 8.5. I get the following error during application start up. The error is regarding guava library and the project is using guava-1.5.jar. I am not sure if its an issue with the particular version I am using. I would be glad if someone could throw some light on this issue.

Guava's Ordering#reverse method has never been final in any Guava release. It's only been final in a very, very old version of Google Collections: https://code.google.com/p/google-collections/source/diff?r=98&old=92&path=/trunk/src/com/google/common/collect/Ordering.java
So you should look for google-collect*.jar in your classpath and get rid of it. It really has no purpose for existence any more.
