Description Desafio Adventure Company CLA 2018-10-05 12:47:06 EDT 
When I open a file with a big lines, it's very very slow. 
And when I try search it's very very slow. 
For example a file has 124.851 characters in a same line. 
Please help me. Thanks

This is known limitation of JFlex. It have a problems with very long lines.

For now we can't fix this without own lexer.

Are you planning fix it?

Extremely long lines is very uncommon use case so it's not our priority. 

Anyway this is not related to JFlex. I made test on one of my symfony controller and checked profiler. Eclipse stuck on SWT, not on our parsers. 

Works better if you disable whitespace printing and highlighting current line, but still unacceptable. I'll try find correct eclipse bugs later.
