Here's a solution that worked for me:
- Open a new finder window and navigate to
/Library/Internet Plug-Ins/. There you will find a file namedJavaAppletPlugin.plugin. - Control + Click this file and choose
Show Package Contentsfrom the contextual menu. - Inside the package, navigate to
/Contents/Home/bin/. - Double click the
ControlPanelfile to display the Java Control Panel. Change any settings as you wish and then save it. - From now on, the panel will be available as always from
“Apple” menu > System Preferences...
Note: if you don't find the JavaAppletPlugin.plugin file inside the /Library/Internet Plug-Ins/ folder, open the Terminal.app and create a symlink from the original:
sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

They removed Java Control Panel in
Java 11.
Open this release notes Removal of Java Deployment Technologies, it says
The Java Plugin and Java WebStart technologies that were deprecated in JDK 9 and marked as candidates for removal in JDK 10 have now been removed. Please note that the Java Control Panel, which was used for configuring the deployment technologies, has also been removed along with the shared system JRE (but not the server JRE) and the JRE Auto-Update mechanism. More details are available in this white paper.
Also, If you go through this web page, JDK 11 Is Released!
There is the last bullet point where it says
The deployment stack, required for Applets and Web Start Applications has been removed. This includes the Java Control Panel used for configuring the deployment technologies, the shared system JRE (but not the server JRE), and the JRE Auto-Update mechanism.
The previous image we used allowed us to switch between "very high" and "high" in the java security pane. This fixes the issue. Currently on this new image it's grayed out, so we cannot access any of these management sites.
This is due to the current configuration of the Windows image you are using. You will have to find and locate the deployment.properties file and remove the following line from the file.
I've tried numerous solutions after some extensive googling and finding where java's settings are stored but the (windows\sun\java\deployment) folder is empty.
deployment.security.level.locked
The Java configuration deployment file can literally be located in any location on the system. You need to find the deployment.config file on the system. This file defines the location of the properties of the Java configuration. You should contact whomever created the Windows image in question for more information.
If you want to override the settings, create your own deployment.config and deployment.properties, then deploy them to C:\Windows\Sun\Java\Deployment. You could also just add the sites to the exception list.
We had this issue today (Oct. 22, 2019) on a MacBook Pro running Catalina. Specifically, after having installed the latest version of Java, the security settings "High" and "Very High" both were grayed out and could not be selected or changed by the user.
We tried the following and it worked! We uninstalled Java (by running the installation app and selecting "Uninstall"), including deleting the cache files, and then reinstalled Java from scratch. Now the security settings "High" and "Very High" are no longer grayed out, and they can be selected or changed.
We previously had installed Java on this Mac, but it somehow had disappeared and was no longer there. So maybe something got glitched with Java along the way, and/or in installing the new version "over the top" (which always has worked).
Doing a complete Java uninstall, including removing the cache files, and then reinstalling fully fixed the problem.
I realise this is an old post but I have recently had this issue in a corporate environment when using MS EMET 5.2 and it was because DEP was enabled in EMET. Removing the tick from DEP in the EMET GUI returned the Java control panel.
I had this problem before with jre6 u45 32bit. By coincidence i found this repeatable solution: It works for me.
- Open Display Settings.
- Go to change ClearType-Text.
- In the ClearType wizard enable and then disable the ClearType checkbox.
- Click next.
- Choose a textsaple that differentiates from the one marked by default
- Repeat this in the rest of the steps of the wizard.
- Click finish and close the wizard.
- Try to open Java Control Panel.
- It should now Open.
Hi Tommy,
It isn't occurring on a specific application that I can tell, if it is, my best guess is it has to be something operating in the background, as its occurring as soon as i turn my pc on, and every time I close the error, no matter if i have any apps open or all closed, the error will keep re-appearing.
When I get the time I'll try the above suggestions.
Thanks.
Hello joseph tampin.
Welcome to Microsoft Community.
Regarding to your information I assume that you have some issues when you use the insert image option.
Based on your description, it seems to be a JAVA environment-related issue. Could you please let me know which software you were using
when you encountered the problem?
I suggest trying to reinstall and configure the JAVA files following the official documentation provided by Java.
Java Technology Help - Installing Java
If you are encountering this issue in a browser, you can also refer to an article to see if its solutions can help resolve the problem.
Update Java runtime settings on Windows
If you're unable to solve it, I recommend reaching out to Java's official support for further assistance.
