Warning messages using java azure client

Using azure-storage-blob-client, I see these:

Why do I get these warning messages?

Turns out one of my dependencies was a "shaded jar" including the jackson components. This shading processes apparently stripped from the jar some kind of version info of which version of jackson was defined. It could safely be ignored.

Sonarqube 7.9.1 refuses to start after an upgrade from 6.7.7

The previous version of SQ was 6.7.7 LTS, so i upgraded to 7.9.1 LTS.
I installed a new JDK
java version "11.0.4" 2019-07-16 LTS

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.4+10-LTS, mixed mode)
but still SQ stopped.

of course i start SQ (and ES) with a non-root user. That’s why i don’t understand the error in es.log
I can't find the solution at all. Please can you help me?

SpringBoot Project build failure with Open JDK 11.0.2 in Intellij 2019.1

I recently upgraded my project from Oracle JDK8 to OpenJDK 11.0.2
Java Version in my system
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)
When I build my project using maven from the terminal it compiles fine but is failing while building the same using IntelliJ. There is no stack trace to look upon, every time I build the project it shows me this error.
This says it's a NullPointerException and I know we have lots of duplicate questions on SO for the same, I am not asking to resolve NullPointer but instead if someone can help me just figure out a way to check the logs while building the project using play button in IntelliJ, I will help myself afterward.
I checked the idea.log file and there is nothing to be suspicious about.

Disabling "Atlassian Clover for IDEA" plugin helped in this case.

In my case it was due to
<arg>-J--permit-illegal-access</arg>
flag in maven-compiler-plugin.
Checking intelij logs also helps
Help -> Collect logs and diagnostics data
in InteliJ menu

Swing Application not launching when trying to test with robotframework

I am trying to run some automated tests on a swing based java application using the robotframework's swing library. I think I have got all the libraries installed. However, when I run the test it is unable to actually launch the application properly (i.e. the fail tests), and I am getting whole bunch of warnings(?) before the test actually starts. Also, I am briefly see the Java icon appear on the dock, but no window actually opens.
I don't have any problem with testing the demo application here though. That works fine.
Below is my robot script:
*** settings ***
Library SwingLibrary
*** Test Cases ***
Test Push Button
Start Test Application
*** Keywords ***
Start Test Application
Start Application com.xyz.app.ui.MainFrame
Select Main Window
Here is the output:

Also, I have verified that the app.jar file does in fact contain the path to the MainFrame class: com/xyz/app/ui/MainFrame.class
UPDATE:
Using "Start Application In Separate Thread" keyword instead of "Start Application" gives a new error. It seems that it can't find the main class, even though I have manually confirmed the path of the main class by unzipping the jar file.:

Following solves the issue:
Setting CLASSPATH using export instead of defining it inline.
Using the fullpath to the .jars.

I have been struggling for a couple of hours to solve this problem but couldn't figure out. Can someone help me out? Thanks!

Try installing the Java 7 JDK and you may have better luck. Although the release notes for Scala 2.10.2 seem to be missing, 2.10.4 doesn't support Java 8:
New ByteCode emitter based on ASM
Can target JDK 1.5, 1.6 and 1.7
Emits 1.6 bytecode by default
Old 1.5 backend is deprecated
...and even 2.11.x only has experimental Java 8 support:
The Scala 2.11.x series targets Java 6, with (evolving) experimental support for Java 8. In 2.11.1, Java 8 support is mostly limited to reading Java 8 bytecode and parsing Java 8 source. Stay tuned for more complete (experimental) Java 8 support. The next major release, 2.12, will most likely target Java 8 by default.
Also see: Can I use java 8 in an mixed scala 2.10 / java project built by sbt?
