Eclipse hangs when opening a minified CSS file in CSS Editor

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.

Riproduci il blocco aprendo fontawesome.min.css del report nel CSS Editor, quindi confrontalo con l’editor di testo semplice e la navigazione dalla ricerca globale. Segui il percorso di apertura del CSS Editor e misura la reattività con il file contenente la riga lunga; il lavoro è completato quando questi file possono essere aperti o raggiunti dalla ricerca senza che Eclipse smetta di rispondere.
