Universal installer, step 4 states:
"JBoss Developer Studio works with Java 6 and 7 and has been tested with OpenJDK, Oracle and Apple JDK."

According to the approved QE test plan (mojo DOC-932620):

• Only Java 7 and Java 8 are supported for running the IDE (Java 6 support for app development only)
• Apple JDK (which is Java 6) is not supported for running the IDE; it's supported for app development only

For clarity, suggest changing text to:
"JBoss Developer Studio can be run with Java 7 and 8 and has been tested with OpenJDK and Oracle JDK."
