Description Sebastian Dietrich

Build Identifier: 20110218-0911

I have opened a lot of editors (~450)  since I had do to a small refactoring on a lot of files. Eclipse crashes with a "no more handles" exception.

Since opening such a huge amount of editors is nonsense, eclipse should either automatically close the least recently opened files or make sure that the number of opened handles (1000) is not exceeded

Reproducible: Always

Steps to Reproduce:
1. open a lot of editors
2. eclipse crashes with a "no more handles" exception
3.

This functionality is available on the Editor's preference page (Window -> Preferences -> General -> Editors, see "Close editors automatically".

   This is disabled by default. Should IDE enable this option by default and set it to some value?

It is limited to max. 99 editors - maybe the default value should be 100 which can only be reduced.
