(JDK 8 supports -source 1.4/-target 1.4, while this support was removed in JDK 9, see JEP 182: http://openjdk.java.net/jeps/182 ) Sorry, but building on JDK 9 is not currently supported. > Why are those outdated targets set? > In some cases, these were set long time ago, and not changed, as it wasn't needed. In some other cases, like the openide.util.enumerations, the sources are actually using a 1.4 features ("enum" as an identifier, not a keyword) for backwards compatibility reasons (and in case of openide.util.enumerations, it might be OK to stop building it). In yet other cases, like java.j2seplatform/probesrc, there is a good reason to use an old -target setting. In the probesrc case, this defines the oldest JDK/Java platform that the IDE will ever be able to recognize as a Java platform. In this case, I am not sure if we can drop support for developing projects for any Java platform older than JDK 6, I would not take such a decision lightly. OTOH, for the probesrc, it is only a single class, which we could generate using other means.
