Hello @veemat1 you may ignore these warning messages because they do not hamper any functionality of AEM. You may suppress the warnings. Thanks, Bilal.

[veemat1]

Thanks for your help. Yes install works, but not sure why so many warning.

[Nikhil-Kumar]

@veemat1 

Warning will not hamper the overall working of AEM server. 
Just verify some of it's basic functionality before building an end-to-end application.

Thanks,
Nikhil

I think these messages are due to JAVA 11

These messages can be ignored because they do not impact the AEM use or functionality.

Hi @arunpatidar 

I am facing same issue, but AEM instance is not up and running. Because of above warning issue?

Hi

The AEM is started and running and you are getting 500 error.

Could you please check the error logs?

[arunpatidar]

you need to install ACS common since you are using version clientlibs feature from ACS Common.

org.apache.sling.engine.impl.SlingMainServlet service: Uncaught Problem handling the request
org.apache.sling.api.SlingException: Unable to setup processor: Unable to get component of class 'interface org.apache.sling.rewriter.Transformer' with type 'versioned-clientlibs'.

[papenaarun]

acs-commons is already installed. I added the dependency in pom.xml

[arunpatidar]

Can you check if packages are installed in AEM and ACS Common bundle is started?

[papenaarun]

It was working fine. Once I restared the system, I am not able to open any of the Page URLs of AEM Server.

Be it, AEM login page, crxde or package manager nothing is getting opened.

When I checked the log, I was getting the error which I pasted above.

Probably, need to check by doing offline compaction once.

[anitha23]

same issue for me. let me know the solution. because for me its working fine for 2 days. after that can able to open any page inside content. but crx/de is open when i directly going to this url ->http://localhost:4502/crx/de/index.jsp. 

[Love_Sharma]

Hello community,

For future visitors, when this happened with me, after warnings my start up process was getting terminated. So my AEM was not starting even after warnings. 

I deleted my quickstart folder and ran java -jar aem-author-p4502.jar command and it worked. My AEM started with the warnings. Only issue here is if you have huge content already deployed to your instance will be gone.

Thanks

Love Sharma
