My group has switched from using JDK 8 to JDK 11. Beforehand, we would adjust our web proxy settings through the Java Control Panel utility (
javacpl.exe). However, we are unable to locate this tool within the JDK 11 files, as there is no
jre folder present. We are curious if the utility still exists within OpenJDK, possibly under a different name, or if it has been removed entirely.
Java has been a popular programming language for many years, and it has undergone several changes and updates over time. One of the latest changes is the release of JDK 11, which has caused some confusion among users. One of the questions that have been asked is whether the Java Control Panel is still included in OpenJDK. In this blog post, we will explore this question and provide you with the information you need.
What is OpenJDK?
OpenJDK is an open-source implementation of the Java SE platform. It is licensed under the GNU General Public License, version 2, and is available for free. OpenJDK is the reference implementation of the Java SE platform, and it includes the Java Development Kit (JDK) and the Java Runtime Environment (JRE).

Changes in JDK 11
With the release of JDK 11, some changes were made to the way Java is packaged and distributed. One of the changes is that the JRE is no longer included in the JDK. Instead, users are expected to download and install the JRE separately if they need it.
Java Control Panel in JDK 11
Due to the changes in JDK 11, the Java Control Panel is no longer included in the JDK. This means that users cannot launch the Java Control Panel using the
javacpl.exe file, as it does not exist in the
If you need to configure network settings or other Java-related settings in JDK 11, there are alternative solutions that you can use. One solution is to use command-line options when launching Java applications. For example, you can use the
-Dhttp.proxyPort options to set the HTTP proxy host and port.
Another solution is to use system properties to configure Java settings. For example, you can set the
http.proxyPort system properties to configure the HTTP proxy host and port.
In conclusion, the Java Control Panel is no longer included in the JDK 11. This is due to the changes in the way Java is packaged and distributed. However, there are alternative solutions that you can use to configure Java-related settings in JDK 11, such as using command-line options or system properties.
