Tomcat Caused by: java.util.zip.ZipException: error in opening zip file

I have a spring mvc project, but it throws out Caused by: java.util.zip.ZipException: error in opening zip file when I run it by Tomcat. How to figure out which jar file has not been loaded correctly.
I have added -verbose:class to VM options, but it only prints out Loaded jar, not the error one.
Tomcat version: apache-tomcat-8.5.23
JDK version: jdk1.8.0_152
Spring version: 4.3.3.RELEASE

Given you have access to a Bash terminal, you can try this one-liner to test your jars assuming they are all in the same directory
for j in $(find /path/to/lib -name '*.jar'); do jar -tvf $j > /dev/null 2>&1; [ "$?" -ne 0 ] && echo "$j jar is broken"; done
Result:
/path/to/lib/test.jar jar is broken
/path/to/lib/some.jar jar is broken

This is an older thread but I just ran into this issue. It turns out, if you package up your application using tar (rather than creating a war file) on Mac OS and then extract it on a Linux server, you'll end up with a "._libraryX.jar" for every "libraryX.jar". Unfortunately, because Tomcat tries to load every jar in your lib directory, it picks up these additional files which aren't jars at all. They contain extended file attribute data that Mac OS wants.
Have to create the tar file like this to keep those files out of your archive.
COPYFILE_DISABLE=1 tar -cvzf mytomcatapp.tgz mytomcatapp

This exception occurres when your war file is damaged. Not only jar files but also other files in war file may be damaged. In my case, I found a damaged png file and after removing it, war file deployed successfully.
In order to find the damaged file use this command:
jar xvf yourApp.war
By running the command, name of each extracted file, will be printed and when it reaches to the damaged file, it prints the exception. So you can find it easily.

JavaFX, Apache NetBeans 10, no class visible

I want to create a cool app in JavaFX. When I installed NetBeans IDE and did all stuff around, I'm not able to run project, because there is no visible (available Java class).
Create project:
Make sure that Create application class check box is selected.
Try to run my project, but there is no Java class.
Can you help me please guys?
Is there any problem with IDE or with the code?

I had the same problem as you did.
As in the thread already mentioned this seems to be a kernel bug. Updating Ubuntu as usually + running dist-upgrade did the trick for me.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
See here for information what dist-upgrade does.

I am not really sure what I should look into to fix it.

This looks like a mismatch between the API version that the plugin was built against, and the API version of the Gerrit server.
java.lang.NoClassDefFoundError: com/google/gerrit/extensions/events/GitReferenceUpdatedListener$Update
The GitReferenceUpdatedListener.Update class was removed from the API in Gerrit version 2.8.
To fix this you should first check which version of Gerrit your server is running, and then make sure you've built the plugin against the API with the corresponding version.

I followed the instruction and ended up compiling the plugin with both changes submitted in here: https://github.com/vadims/gerrit-owners/issues/6 (look for the 2 forked repo) and it did work.
It was painful but the plugin does an awesome job so worth the effort!
