| Re: [wtp-dev] Nashorn custom class loader OSGI extension not supported by PDE |
There is also some more information on https://wiki.eclipse.org/JSDT/Equinox_hook_for_Nashorn
that may be helpful.

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.
