IllegalStateException: zip file closed

I have a Java desktop application that was running fine in Java 1.8; I'm upgrading to Java 1.11 for a client, and am getting the above error.

The Tesseract library has a Java wrapper that I've used for months successfully but now seems involved in the error, whatever it is. I've been using the same DLL and started getting this failure, and I've updated the Tesseraact DLL and the wrapper to their latest version.
More puzzling is that the application runs fine within eclipse, and only fails like this when run from a command line (Windows 10). I have uninstalled and reinstalled the DLL a couple of times, rebooted the machine each time, and am running out of things to try. I went through the entire Maven dependencies list and deleted all files found there from my repository, then refreshed the eclipse project to reload all the files in the list.
I saw one suggestion of placing a breakpoint in ZipFile, but that won't help since the problem does not appear in eclipse.
I'm willing to upgrade the Java further, but it would be nice, first, to have some knowledge of what the problem is so that I have some confidence that will fix it.
Can someone suggest what might be wrong, or strategies to find out?

I do not use JAXB and I have no idea where does this come from. More frustrating is I can build my app without any error.
I have tried the solutions in the following links, but none of them works for my case.
https://www.concretepage.com/questions/556
How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException in Java 9
Has anyone experienced similar issues?

The JAXB APIs are considered to be J2EE APIs, therefore not present default class path in Java SE 9. In JDK 11 they are completely removed. But, these Java EE APIs that were provided in JDK 6/7/8 are still in the JDK.

Edit 10/2020:
I ran into this issue again some time ago when CircleCi update their java image from jdk8 to jdk11. I was able to solve this issue by updating the Gradle tool. Looks like in the latest version of Gradle lint no longer use JAXB APIs.
Old answer: Today I finally solve this issue. Here is what I did.
I attempted to solve this issue by reinstalling Android Studio 3.4. However I couldn't even start up Android Studio and I ran into this
java.lang.RuntimeException:
com.intellij.ide.plugins.PluginManager$StartupAbortedException:
Fatal error initializing 'com.android.tools.idea.AndroidInitialConfigurator'
Then I looked for answers and came across this page
[Can't start Android Studio][1]
[1]: https://superuser.com/questions/1391452/cant-start-android-studio
I reverted back to use jdk 8.
Android Studio 3.4 finally started up, and JAXBException was gone.

Redhat is not listed as as supported configuration for JavaFX 2.2.
Nor is running JavaFX in a headless mode.
This may change for Java 8, but Java 8 has not been released yet, so the list of supported configurations for JavaFX running on Java 8 has not been published.
Currently the supported configuration set for Linux is only => Ubuntu 10.4+ gtk2 2.18+ with optional additional requirements for av codecs if you also want media playback support.
So try using a supported Ubuntu system instead of Redhat and you may or may not get that working in a headless environment.
I tested and it works fine with Redhat 6. Redhat 5 seems to be the problem.
Redhat Enterprise Linux 6 support will be added for Java 8 (to be released in the next few weeks).
A RHEL 5.5 support request was closed as won't fix, see RT-22564 "JavaFX Support for Red Hat Enterprise Linux 5.5".
If you can find a way to install gtk2 2.18+ on RHEL 5 you may be able to get it to work, though no promises.

Android - Processing Build not compiling

I'm having issues with the IDE Processing.
I'm trying to compile something to Android. I'm on Android Mode, of course. But I'm getting this Error at the time of compiling. (It's not the code itself)
I've installed "adb devices", it seems Ok. I've done all the "51-android.rules" process. I've installed API 10(the one requested) and Android Tools. I don't really know what should be wrong.

I've been experiencing this issue as well, and apparently there are 2 possible causes:
Apparently the location of aapt has been changed by a recent version of the SDK tools, v22. I'm not sure if removing that version of the tools would fix it, or if that would be recommended. This thread has some fixes that might work.
If this doesn't fix the problem, you may be trying to run the 32 bit aapt on a 64 bit system without the 32 bit runtime installed. In this case the fix from this thread may fix the issue:
sudo apt-get --no-install-recommends install ia32-libs-multiarch
In my case, only the second of these fixes was necessary. By the way, I should point out that I was building android via Phonegap, so the use case may not match 100%. However, the same problem was occurring on the exact same line, where ant tries to execute aapt.
(Aside: The problem isn't necessarily on line 690 specifically, I think that line 690 is just given because it's the end of the "clause" specifying the execution of aapt.)

Using NetBeans 6.5 and running Java 1.6 on Mac OS X 10.5.6

Apperently this is a NetBeans issue for Mac OS X...
Answer from netbeans forums

If you make a new NetBeans module project and simply run that does it work? (trying to narrow the issue down, and eliminating anything but the absolute basics is a good place to start)

Looks like your target platform is set to JDK 5 but your module is built against JDK 6.
