AEM 6.0 having some issues with java 1.8.

[vishwanath881]

Hello All,

In my current project, I am installing AEM 6.0 with Java 1.8. I have also installed service pack 1 and service pack 2. But after I do a maven build successfully, when I try to load the page it always fails and shows the following error.

Initially, it worked fine but later I don't know why it started failing.

com.day.cq.wcm.tags.IncludeTag Error while executing script body-section-header.jsp
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 38 in the generated java file
Only a type can be imported.

Check if the Java class referred in the JSP is also been compiled in JAVA 8

Your description indicates some reinstallation happened either at os level (jdk upgrade or envirnoment variable modification) or at aem product level.  Without complete logs & call tough to find out.  File an official support request.

You can't install AEM 6 with 1.8. First you have install it with 1.7 and then apply service pack 1 or 2 which both support 1.8. After you have applied the service packs you can shut down and then restart using 1.8. The compilation error is what happens when you try to run a base AEM 6 with 1.8 without applying the service packs.
