This is a heads up for anyone else who may come across this email when searching for my stack trace below. I spent a bit of time trying to figure out what went wrong, and I am not the only one ( https://www.eclipse.org/forums/index.php?t=msg&th=1076119). If anyone knows a better solution to this problem than I outline below I would be grateful.
When using JSDT setup in a PDE target platform you can get an exception java.lang.NoClassDefFoundError: jdk/nashorn/internal/runtime/ECMAException when opening JS editors in the runtime Eclipse. This does not happen in a properly installed Eclipse because the classloading hooked in with https://wiki.eclipse.org/Adaptor_Hooks is done by P2 when it installs the org.eclipse.wst.jsdt.nashorn.extension bundle. P2 automatically updates the config.ini with the osgi.framework.extensions setting pointing at org.eclipse.wst.jsdt.nashorn.extension. PDE does not know about this (see http://eclip.se/271189), so if your target platform has JSDT in it, the config.ini generated by PDE does not have osgi.framework.extensions set. To be more precise, it works fine if the target platform is setup to point to an existing installation having JSDT installed properly because PDE inherits the config.ini in that case. But if the PDE target platform is pointing directly at the P2 site, PDE does not handle that case. The solution is to add -Dosgi.framework.extensions=org.eclipse.wst.jsdt.nashorn.extension_<version>.jar to the vmargs of the launch configuration. You can add this to the launch configuration, or to target file in the Environment tab, but the latter will not affect launch configurations that were created before editing the target file. I cannot figure out how to make the version or full name of the bundle a variable so that it does not have to be updated. Nor do I know how to set this up from a TPD ( https://github.com/mbarbero/fr.obeo.releng.targetplatform) file.
