still, companies do things like that - switching an application from perl to java. in 1/2 year or so.

reasons:
"java is more widely used and has working frameworks" - old problem with chicken or egg - if more companies supported perl development there would be more frameworks
"you will get more/better support just because there are more people who know java" - same problem
"why do you complain? a computer scientist is not a language-x-programmer but a programmer who can program in any language" - well, why don't we all program in bash, then? the point is not to *be able* to program in a language but to think that a language is the better tool

perl is often seen as a script-kiddie/unix-admin language, like "if you want to do some real business, you don't play around with perl".
