I just did a minor upgrade, and then I suddenly started having Java Problems.

The stack trace looks like:

I have both openjdk-11-jre and openjdk-11-jre-headless installed as well as libatk-wrapper-java and libatk-wrapper-java-jni installed.

The java code I'm using is an old program I wrote myself, but it was working fine until the last update.

I can make the problem go away by commenting out the line in /etc/java-11-openjdk/accessibility.properites, but I suspect that there is a broken dependency in one of the packages I recently installed.

The following packages were installed in the update:

Upgraded the following packages:
accountsservice (0.6.45-1ubuntu1) to 0.6.45-1ubuntu1pop2
console-setup (1.178ubuntu2.3) to 1.178ubuntu2.6
console-setup-linux (1.178ubuntu2.3) to 1.178ubuntu2.6
gir1.2-accountsservice-1.0 (0.6.45-1ubuntu1) to 0.6.45-1ubuntu1pop2
gnome-initial-setup (3.28.0-2ubuntu6.16.04.1) to 3.28.0-2ubuntu6.16.04.2system76.1
keyboard-configuration (1.178ubuntu2.3) to 1.178ubuntu2.6
libaccountsservice0 (0.6.45-1ubuntu1) to 0.6.45-1ubuntu1pop2
palemoon (27.9.4~binaryrepack-1) to 28.0.0~repack-3

As the error is gnome related, I'm blaming the gnome-initial-setup package, but I'm wondering if anybody knows more about this than I do.

There is a known bug with the openjdk atk wrapper, so it's not really a gnome problem. The openjdk bug says it was introduced in openjdk9, though a google search shows it as early as openjdk8. The bug has been closed, with a external classification, requiring the ATK to be re-engineered as a service.

The workarounds are either comment out the assistive technology line in the accessibility properties file, as you stated, or add the wrapper to the classpath

export CLASSPATH=/usr/share/java/java-atk-wrapper.jar

The openjdk bug reference is https://bugs.openjdk.java.net/browse/JDK-8204862
