I don't know much about JBoss 4 but the common practice when ports install different stuff depending on JDK version is to use a PKGNAMESUFFIX to indicate the JDK version used (e.g. '-jdk14'). java/openjit is one good example. > I'm not sure if it is possible or even reasonable to change the current > behavior (I'm overriding JAVA_PREFERRED_PORTS), but perhaps we could add > an informative message when building the port to inform the user. I can think of two approaches here. Either we disallow Java 1.5 (since there seems to be trouble with it anyway, as you describe above), or we could just enforce JAVA_VERSION?=1.4 and let the user know that he may override JAVA_VERSION if he wants another JDK version. Indeed users don't always read the messages from the install log and the JDK that is picked up does not only depends on JAVA_PREFERRED_PORTS (it also depends on the JDKs that are installed at the time you install a port). So I think it's better to enforce a known-to-be-stable flavor of the port and allow the users who know what they do to request a different flavor. I also wondering what could happen if you use java/jdk15 to build the port and then java/jdk14 to run it... In case this causes trouble, it would confirm the fact that we need to enforce either "1.4" or "1.5" (thus no "1.4+"). Herve
