Description Jens Reimann

2020-06-22 08:04:52 EDT

Starting 2020-06 I get a NPE when opening a shell script in Eclipse. It still opens the system editor, but a dialog pops up and the following exception is logged:

~~~
java.lang.NullPointerException
	at org.eclipse.epp.internal.mpc.ui.discovery.DiscoverFileSupportJob.orderNodesByTagSubExtensionCount(DiscoverFileSupportJob.java:126)
	at org.eclipse.epp.internal.mpc.ui.discovery.DiscoverFileSupportJob.run(DiscoverFileSupportJob.java:87)

Same error when trying o open a .spec file.

Thanks for the report. Does this happen for any file with those extensions? Could you give me a concrete file name?

It looks like we get search results from the server that have no tags at all, let alone the ones indicating .sh/.spec editor capabilities.

In any case, I can see where the NPE happens and will have a fix in one of the upcoming builds.

As a workaround until a fix is available, you can set an editor association explicitly to suppress the Marketplace lookup for the affected file type:

- Right-click on a file with the affected extension in the Project/Package Explorer
- Choose "Open with... / Other..."
- Select an editor to use
- Check the "Use it for all *.ext files" or "Use this editor for all Name.ext files"

FYI: MPC 1.8.4 with the fix has been released. You should be able to get the update via the Marketplace Client UI's update banner.
