Bug: Insight login window is broken on login failure with OpenJDK6

[rleigh]

If the login fails (invalid username or password), the dialogue becomes unusable. All buttons are deactivated with the exception of the "Quit" button, the entry fields are greyed out, and a busy clock cursor is displayed. This makes it impossible to do any action other than Quit! Reattempting the login is not possible without quitting and restarting the application.

This appears to be an incompatibility with OpenJDK, since this works correctly with Oracle JDK.

Note that logins are possible, providing that the username and password are correct on the first attempt.

Blazej found that this works correctly with OpenJDK7. However, this is not the default on most distributions using OpenJDK.

This should go in the openJDK section. we have several problems. Pushing

Realistically we won't be able to work on it for 4.4.9

I am seeing this problem too:

My problem is slightly different: I can't type into the login window even on the first attempt, though I can still click the buttons. Using Linux, Insight with OpenJDK 6 or 7 is wholly unusable for me, immediately in the way described above as being for "if the login fails".

[mtbcarroll]

The problem seems somewhat intermittent for me. My experiments indicate that I can't type into the login window only if it has lost focus at any point.

[mtbcarroll]

Simon's research indicates that this may be window-manager-specific. I'm using ctwm, though I've been using it heavily since the 1990s without seeing any other problems like this. I'd guess next steps could be (a) see if I can construct a minimal Swing app that reproduces this or (b) look hard at if there seems to be anything odd in how Insight is running the dialog.

[mtbcarroll]

Hmmm, the login dialog is certainly an unusual window for me in xprop reporting of it,

Client accepts input or input focus: False

[mtbcarroll]

Probably it is also relevant that WM_PROTOCOLS includes WM_TAKE_FOCUS.

[mtbcarroll]

My problem turns out not to be Insight-specific: the small test program at ​http://bugs.sun.com/view_bug.do?bug_id=6798064 exhibits exactly the same behavior for me.

Should we close this as wontfix since it's for OpenJDK6, and most users should have access to OpenJDK7?

[rleigh]

There is a separate ticket already open for the focus issue.
