the abbreviation of "main" does not work, why?

Hi,

I use the latest version of JDE with the JDK 1.6.0, installed in a debian
linux.

The JDE is installed by performing command "aptitude install jde".

Now, the problem is:
As I type the "main", the abbreviation of "main" does not work; however,
other abbreviations (e.g. for, fori, try, and so on) all work correctly.

Does anyone encountered or known this problem? I fairly appreciate such
functionality.

thanks in advances.

Erik, Wang
