A fresh install of Eclipse 2021-06 can’t start with DevStyle installed, if running on Java 16. With Java 11 there seems to be no such problem. Looking at the console there are a lot of exception stack traces like this:

Hi,

Apologies for the delayed response. We tested DevStyle on the same environment as yours and could not replicate the issue.

Can you please try starting Eclipse with -clean command args and check if it starts fine? You can add -clean as first line to the eclipse.ini file located in the Eclipse installation directory or run this command from command line : eclipse.exe -clean

If the above suggestion does not help, then please share with us the exact Eclipse distribution details (CDT/JEE etc) and the complete log file to help us get the full list of errors. Also let us know if any other third party plugins are installed.

Apologies for inconvenience caused.
