Eclipse hangs when opening a minified CSS file in CSS Editor #656
Description
When I open a minified CSS file, i.e. with one very long line (e.g. 80k characters), Eclipse hangs with 100% CPU load.
The severity is different for different files of similar length, probably depending on the content. For some, Eclipse hangs for about a minute, which allows you to close the editor without killing Eclipse, e.g. fontawesome.min.css from https://fontawesome.com/download .
Others, like a proprietary file that I can't share, make Eclipse sleep for at least one hour (maybe forever).
While I can consciously avoid opening these files, it is especially annoying in a global search, when clicking next takes you to such a file without a warning.
When I open the same file in the plain text file editor, the CPU load goes up to 100%, too, but Eclipse gets responsive again much faster.
