Re: "AtkWrapper not found" error impacting JOSM on Ubuntu/Mint
Hello, The bug is closed so there is nothing to expect from OpenJDK. The solution must come from Debian or a new bug created. The Java version which introduced the regression is 10.0.2+13-Ubuntu-1ubuntu0.18.04.1 because it contains the fix to move accessibility.properties in the "conf" folder. The issue did not occur before because the configuration file enabling ATK wrapper was not found by openjdk. A few hours after this version was delivered by Ubuntu we started to receive a dozen of bug reports, until I delivered a JOSM hotfix mitigating the issue. Patching openjdk with your try/catch proposal and making the ATK wrapper a Recommends sounds a good idea. Don't wait for openjdk guys for an answer: they simply don't care anymore with desktop technologies.

Re: "AtkWrapper not found" error impacting JOSM on Ubuntu/Mint
JOSM 14178 has been released as new tested version to workaround this problem. Samuel, do you know when the root issue will be fixed in Java ATK wrapper? Has it ever been considered that this package is made optional rather than a strict dependency of openjdk--jre? Most users don't need it.

Re: "AtkWrapper not found" error impacting JOSM on Ubuntu/Mint
I remember too, it was indeed a nightmare and I don't want to live that again. It took me a while but I found a workaround that doesn't need any user action nor any adherence to ATK wrapper. We can just catch the AWTError and try again to re-create our MainFrame. As the ATK initialization fails only after the AWT toolkit has been created, the second call succeeds: https://josm.openstreetmap.de/changeset/14177/josm Kevin, can you please check tomorrow that it works for you too? I'm leaving the ticket open a few days as we will probably receive many more bug reports this week. Right now it's too difficult to disable ATK on Java 10 and remain compatible with Java 8. I'll revisit this topic once we migrate to Java 11.

"AtkWrapper not found" error impacting JOSM on Ubuntu/Mint
Hello, Since today we are spammed by bug reports from Linux Mint and Ubuntu when people try to launch JOSM with the latest Java update (10.0.2+13-Ubuntu-1ubuntu0.18.04.1): https://josm.openstreetmap.de/ticket/1 The error is "ClassNotFoundException: org.GNOME.Accessibility.AtkWrapper". Is it a known issue? We cannot really workaround it unless telling every impacted user to manually disable ATK wrapper in accessibility.properties. Thanks, Vincent
