Hi,

Which version of java you updated and what is the version of AEM you are using? Can you check error.log to see what is the exception/errors you are getting while opening author/publish instance.

Error log will present under /crx-quickstart/logs/error.log.

Please share the error logs which helps us to analyze further on your issue.

Also check After upgrading Java version, AEM does not start up | AEM in case you are facing similar issue.

I updated to java version "1.8.0_151". I am using AEM6.3.

Try Removing the following line from crx-quickstart/conf/sling.properties:

org.osgi.framework.system.capabilities=${eecap-${java.specification.version}}

i TRIED CHECKING THIS. no such line exist. Thank you.

Low-memory action set to fork

Using 64bit VM settings, min.heap=1024MB, min permgen=256MB, default fork arguments=[-Xmx1024m, -XX:MaxPermSize=256m]

The JVM reports a heap size of 1024 MB, meets our expectation of 1024 MB +/- 20

No console, will fork to get enough memory

Not forking JVM as -nofork option is set

Setting properties from filename 'C:/Users/Hemanth/Desktop/AEM6.3-20180223T145720Z-001/AEM6.3/aem6.3-author-p4702.jar'

Option '-quickstart.server.port' set to '4702' from filename aem6.3-author-p4702.jar

Verbose option not active, closing stdin and redirecting stdout and stderr

Redirecting stdout to C:\Users\Hemanth\Desktop\AEM6.3-20180223T145720Z-001\AEM6.3\crx-quickstart\logs\stdout.log

As Ravi mentioned above, allocate more RAM when starting up AEM. If you're using Mac, use top to check RAM used by AEM and assign more using -Xmx2048m or 4096m

It seems to be memory issue, try increasing memory and test. Check below post

trying to install CQ author instance ?

Also check whether system has sufficient free space
