[icedtea-web] not closeable javaws (and maybe more)

[Jiri Vanek]

Hi!

Head, for already some time javaws apps needs to be closed by signal kill. For long time I thought this is soem accident or whatever, but it is not.
Today I tracked it to guilty changeset of  http://icedtea.classpath.org/hg/icedtea-web/rev/6f4c1d501560

Looking for the fix now, but in case I fail, this will spare some time to the followr,

  J.
