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

Some people suggest that the error is due to the Java version, as it seems that Beam doesn't work fine with Java 9. Anyway, I'm still using Java 8. On the other hand, some other people say that the error is caused because you have to provide a subfolder under your bucket as the storage location. I've tried, but it still does not work.
If anyone faced this same issue before or can provide any advice on the error, it would be appreciated.
You should create bucket gs://mysite-ga-datastreaming-196008-my-bucket/ in Google Cloud Storage before use the pipeline.
Create mysite-ga-datastreaming-196008-my-bucket in the GCP Project.
For Bucket Creation :
Go to GCP UI, select Storage Bucket. Click Create Bucket Button. Enter Bucket name mysite-ga-datastreaming-196008-my-bucket. Click ok.
Then run the command.
I can run all test and they passed but when i run with coverage i got error

Why without coverage option they passed but with coverage not? And how can i fix this ?
The java.lang.reflect.InvocationTargetException is occur when underlying method throws the exception. if method which has been invoked/call with reflection API, throwing an exception. and reflection API will wrap exception in to InvocationTargetException which throw by underlying method. for more understanding you can refer below link of stackover flow Question Asked by : user550413 and Answer by many java experts. i think you can get suitable answer on this link.
What could cause java.lang.reflect.InvocationTargetException?
In my case it was casued by non-ASCII characters in Intellij path. The solution is to change directory in Intellij properties:
Workaround:
Add this line
-Djava.io.tmpdir=C:\Temp to the idea.exe.vmoptions file (in C:\Program Files\ideaIU-11.1.4\bin)
And make sure the C:\Temp exists.

How can I resolve this problem ?
It's a system property, so you'd have to do it at a system level, i.e. by adding -Dcom.sun.media.jai.disableMediaLib=true in your VM Options.
Known issue; see https://github.com/NetLogo/GIS-Extension/issues/4
I don't think this error being printed actually affects anything. Is something not working, or are you just concerned about seeing the error message? If the extension seems to work, I wouldn't worry.
My application got stuck, then I wanted to check the thread status. But I couldn't take a thread dump via jstack -l 33822 from my application..
Unable to open socket file: target process not responding or HotSpot VM not loaded
The -F option can be used when the target process is not responding
Then I used -F to attempt to take a thread dump. I got an error as following:
