Fred Bricon commented on JBIDE-20010:
-------------------------------------

Most, if not all these examples target EAP 6, which implements the Java EE 6 spec. And [according to that spec|https://jcp.org/en/jsr/detail?id=316] :
{quote}Java EE 6 is the Enterprise Edition of version 6 of the Java platform, and thus will be built on Java SE 6.{quote}

JBT/JBDS requires Java 8 to run, but is still capable of launching runtimes with various versions of Java, so no, the examples should not be changed. However, I suggest [~sgilda] to document the quickstarts about that warning. More precisely the examples compile with a target version of 1.6, but a higher version of Java is used to compile. The problem here is you might be able to use API from JDK 8 that would break at runtime when running with Java 6. eg. System.lineSeparator() would be available during compilation but isn't available on in Java 6. So users either need to change the minimum Java requirement in their pom.xml or make sure Java 6 is an available Java Runtime in the Eclipse preferences.

> See the attached screenshot - this is not a new issue, but seeing as how we now require Java 8 (http://tools.jboss.org/documentation/whatsnew/jbosstools/4.3.0.Beta1.html#general) - the examples should no longer reference Java6.
