You are probably using the JSON editor from Eclipse Wild Web Developer which indeed requires Node.js to provide JSON support beyond syntax highlighting. Node.js is required to run the JSON language server like Java is required to run Eclipse.

You have the following options:

• Install Node.js into your system
• Install embedded Node.js into Eclipse:
  1. Go to Help > Install New Software...
  2. Work with
  3. Choose Node.js embedder from Wild Web Developer and install it
• Use a different JSON editor that does not require Node.js:
  • Eclipse Web Developer Tools
  • JSON Editor Plugin
  • ...

This error occurs and freezes the IDE (STS 4.7.2) when a dockerfile is opened and node.js is not installed or not in the path. As a solution, I removed all docker related plugins from STS and the problem is solved.
