Recently I got a chance to try Gel - a light weight java IDE written in Delphi. I found it very good. Very light in memory footprint and very fast to load the projects.
Why a java IDE is written anything other than Java? Why not? (any reason other than political reason?). I have found two interesting advantages with Gel.
1) It is natively compiled and (hence) light weight in memory foot print.
2) It doesn't parse and load the whole project at the startup and hence start up is very fast (also attributing to low memory usage).
However the Del project is not active now. As I understand the owner is looking for somebody who can take it forward. If anybody interested this would be very useful.
