After fixing a load of Java 7 related problems the last two days I was
all set to do a new release of my application, but when I did final
check of functionality I noticed that when using FileDialogs they were
opening a slightly different view (not FileDialog not JFileChooser)
and they were indicating busy whenever I selected a folder, and they
stayed busy unless I selected another folder and the select the first
folder again. this was major regression so I spent all afternoon
checking my FileDialog related code which had been changed looking for
what I could have changed that would cause this, nothing seemed to fix
it.
So I then started rebuilding my code from different svn checkins to
try and find out where it goes wrong, and the culprit was adding a
splash screen to the application bundle !
I did have this in appbundle ant file (and I'm sure I've specified it
correctly because the application did correctly show the splash screen
when built with this included )
<option value="-splash:$APP_ROOT/Contents/Java/splash.png"/>
simply removing it and rebuilding and FileDialog now works as
intended, and Ive added it and taken it out and rebuilt each time to
check this because I couldn't believe it first time.
How the two relate I do not know but I would assume splash screens are
pretty common, and the link with FileDialogs is so obscure it will be
difficult for developers to link the issues.
I then found
https://bugs.openjdk.java.net/browse/JDK-8009203
which looks to be the same issue, but the comment
'The issue exists from the jdk7u6 on OS X, so it is not a
regression'
make no sense, it is a regression if moving from Java 6 to Java 7
And the comment
'It is unlikely that the client would notice the problem as
it's quite unusual to open the FileChooser immediately after the
application loads.'
used to justify no fix until jdk 9 is incorrect, the problem occurs
however long you wait. This really should be fixed for Jdk 8 at least
IMO.
