Tested OS : RedHatLinux 7.1/7.2
Winow manager : Gnome
Reproducible test cases : SPI403/404
Reproducible jdk version : hopper fcs, hopper-rc, Merlin FCS


To reproduce,

1. Assign IM selection key.
2. Run SPI403 or 404 test case.
3. Select Host IM.
4. Press shift + space to activate Japanese input mode.
Then, Kana-kanji Conversion window appears.
5. Exit Kana-kanji Conversion window pressing X located at the right top corenr.
Then, the test application abnormally ends with error messages:
Or
sometimes all opened windows dissappears: not only the spi test case's windows, but also the terminal window on which the command for the SPI test case is executed disappers.

At this point kinput2 is defunct:

Trying this test with some previous version of jdk(hopper-rc and Merlin FCS), this is reproducible, so this is not a regression.

This causes java VM aborting and make hostIM defunct, so this seems a severe problem, however, following the instruction of the test cases or pressing shift + space to deactivate Japanese input mode this problem is not seen. I think that it can be a workaround and it is not a showstopper for Hopper FCS at this critical time.

* This kind of problem was seen with other operation also, however, trying many times, I could not specify the reprodubible steps.
I'll continue the investication and I'll update the report when I can specify the steps.
