Bug#798794: Exception in thread "main" java.awt.AWTError

[殷啟聰]

This bug can be seen if you run "draw9patch" of Android SDK even if
you installed default-jdk & libawk-wrapper-java. By following a thread
[1] on Ask Ubuntu I successfully run "draw9patch". The workaround is:

Uncomment ``` assistive_technologies=org.GNOME.Accessibility.AtkWrapper```
in file .

I'm not sure if this is a bug of openjdk-8-jre, but it is surely a bug.

Bug#798794: Exception in thread "main" java.awt.AWTError

[Martin Hanson]

Hi Jan

Thanks for your reply.

Yes, the problem exist when running with "openjdk-8-jre" in which I am getting 
the "ERROR StatusLogger No log4j2 configuration file found. Using default 
configuration: logging only errors to the console." error and the program then 
just hangs.

Hi Martin,

the log message you quote comes from Minecraft itself and not openjdk.
For that problem please contact the Minecraft support, since it is third
party software.

Do you have any exception stack trace from Minecraft in your log? Not
these "ERROR ..." lines.

Best regards,
Jan Henke

I thought as much, but none the less, I can run Minecraft on the desktop with 
only the headless package installed:

$ dpkg -l | grep openjdk
ii  openjdk-8-jre-headless:amd64  8u66-b01-1~bpo8+1   
amd64OpenJDK Java runtime, using Hotspot JIT (headless)

This package is from Jessie backports and everything works. If I install the 
package from Testing then it doesn't work. I also tried installing both 
headless and the normal jre package, but the problem persist, until I remove 
both packages, install the Jessie backport and put it on hold.

Sometimes it doesn't give the above error, but this one instead, then Java 
freezes:

Hi Martin,

this is not a bug. If you want to run any Java application with a GUI,
you need the non-headless openjdk package (i.e. openjdk-8-jre). The
headless package is intended for "headless" machines like servers.
Headless means here system usually running without local monitor,
keyboard, mouse, graphical user interface etc.

So the -headless package, by design, does not include the parts
necessary for running applications like Minecraft.

I hope that explanation helps.

Best Regards,
Jan Henke
