ran problem today while trying create new aem instance. providing fix reference. said in comments issue due java 8. solution run aem jar java 7 using command line.

"c:\program files\java\jre7\bin\java" -xmx1024m -jar cq5-author-p4502.jar pause 

run above command folder cq5 jar present

c:\program files\java\jre7\bin\java needs modified path of java 7 jvm.

-jar cq5-author-p4502.jar should name of jar
