I was running "Refactor | Migrate Ext AS Properties" in instructions https://github.com/CoreMedia/jangaroo-tools/wiki/Migrate-Jangaroo-2-to-4 step 9.

Thread dump attached.

Hi Mikka!

Thank you for your report and sorry about the error.

We just recently also found out that due to an incompatible change in IDEA, the plugin "Jangaroo Migrate to Ext AS 6" does not work in IDEA 2017.

Until we are able to fix this, please use IDEA 2016.3 for migration.

After migration, for development, feel free to use IDEA 2017.

I just updated the migration documentation accordingly.

Greetings

-Frank-
