VERY slow JSF code completion ------------------------------- Key: JBIDE-27315 URL: https://issues.redhat.com/browse/JBIDE-27315 Project: Tools (JBoss Tools) Issue Type: Bug Components: jsf Affects Versions: 4.15.0.Final Reporter: Maycon Oliveira Priority: Major Hi there! Im being using eclipse + jboss tools along the years to develop and maintain a JSF application (the app is getting bigger. Now it has 810 BackingBeans anotated with @Named). I noticed that eclipse /jboss tools is getting slower as new versions are being released at the point that is not usable anymore to autocomplete JSF EL expressions (xhtml file) or to use the ctrl + click funcionality. The IDE *hangs for 20 seconds* every time I execute this commands. The strange part is that when i use the ctrl + space to autocomplete an expression that is not closed by the "}" marker, the result apear really fast. Ex:     FAST CTRL + SPACE COMPLETITION AT '.' value="# {admUsuarioBacking.selectEntity                 SLOW CTRL + SPACE COMPLETITION AT '.' value="#\\{admUsuarioBacking.selectEntity} "   My enviroment: Eclipse 2020-03 with JBoss tools Wildfly 20 Linux Mint 19 Notebook Dell Gaming with i7 processor and 16gb RAM   Thanks
