Michael: Thanks for the response.
You wrote: "Is your ant script or your Eclipse settings deciding which compiler version you are using ?" I believe it depends on how the JAR file for the plug-in is produced. If you compile and build the Jar using Ant from inside Eclipse, then Ant controls. I checked my tools.jar in the Ant Runtime Configuration, at it is being pulled from a 1.6 JDK. This should be the same Eclipse is using. I also tried creating the JAR using the export command in Eclipse, without Ant, and I get the same exception I do when using a JAR created with Ant. You wrote: "Does your GPX plugin have dependencies ?" It does. Most of those are pretty old. I'll have to double check and see if any of the dependencies are compiled for Java 1.7. The exception is thrown when I try to call the configure method of the Extension for my plug-in. However, if OJ loads all the dependency classes into the JVM when the configure method is called, that could be the problem. You wrote: "Did you try to remove (or no rename) you java 1.7 installation while compiling, just to make sure you're not using it ?" I'll try this. Not a good long term solution, as I need a 1.7 JDK for other work. Worth a shot though. You wrote: "Why don't you stick to java 1.5 as we do for OpenJUMP and most plugins ?" You can't even download the 1.5 JDK or JRE from Oracle's web site now. You have to get it from an archive web page which requires an Oracle web site registration. OJ is running and compiling OK for me on Java 1.6, so I'll be happy if I can just get that to work. I'll have to let the plug-in users now that Java 1.6 is required.
