Hi,

Asian input method IME/FEP start/toggle keys in use are:
  shift-space:   older Japanese UNIX-like OS and some Windows pre-MS-IME tools
  control-space: older Chinese UNIX-like OS
  control-enter: I see web document mentioning Solaris used to do this.

And all these shift/ctrol/alt/-space/enter/... combination were used by
text input method.  This is highly desirable keys which OS-level utility
like to take control.

Yes.  So what is wrong here.  You filed this not as wishlist but normal
bug.  I fail to understand rationale behind your reasoning eclipse
should own this key binding.

I found:
http://superuser.com/questions/327479/ctrl-space-always-toggles-chinese-ime-windows-7
http://lists.tlug.jp/ML/9810/msg00259.html

So this key combination is liked by many apps and tends to conflict
with popular cross-platform input method change method convention.

UNIX-like input method for Japanese used shift-space in old days with
xim+kinput2 etc.  (At least from 1998)

Please provide reference for history.

ibus is following Chinese input method tradition as I understand which
use ctrl-space.  (Japanese seems to use shift-space.)
  ibus: 2008-05-12 and since then uses ctrl-space
  scim: 2003 and since (precursor to ibus and uses ctrl-space)
  I am sure some chinese IM used this before 2000.

  eclipse:  2002 not so old.

This is 2013.  No one except you complained this for 5 years.

Also as I see web for Mac:
Command+Space seems to be choice to switch IM for MAC OSX. (MAC-command==WIN-control)
http://apple.stackexchange.com/questions/15173/changing-keyboard-input-language-on-mac-osx

So this is not situation where very common cross platform OS level
convention for basic UI needs to be changed just for an application.

Or changing eclipse key-binding, you get the same coexistence.

This is not normal BUG for ibus for sure.

This is at best wishlist bug with wontfix attached.

Usually, this tag is used for PO translation etc.  This is not needed.
