Hi,

Sorry that you are seeing this issue. Thank you for the stacktrace and the details.
I am afraid it is an Eclipse issue and not a DevStyle one. I checked with a fresh install of STS 3.9.9 without DevStyle plugin and see the same problem as reported by you. We fixed it specifically in MyEclipse.

CodeMix, our latest Eclipse plugin brings VSCode smarts to your IDE. It gives you a better development experience with existing tech like HTML,JS,CSS and Angular along with supporting all the latest tech like Vue, React among dozens of others. Please see this link for more details : https://www.genuitec.com/products/codemix/

CodeMix is free with existing paid licenses for MyEclipse Professional and higher. You can install CodeMix to MyEclipse from the Marketplace or using this update site : http://www.genuitec.com/updates/codemix/ci/

Please give it a try and let us know if you see any problems.
