Sharing my own solution just in case anyone else has the same issue.

That cipher is actually available in the /lib/ext/sunjce_provider.jar file on the openjdk compilation (IBM Semeru Runtime Open Edition (build 1.8.0_322-b06)).

As posted on the question, it's actually on the provider list (index 6), but the jar was not being loaded. I have yet to investigate if there is any change on the extension classloader that I'm not aware of, but, so far, manually adding that jar to the application classpath has worked flawlessly and got the cipher working.

The problem here is that the API and SPI bundles that start with io.openliberty have not been publishing to DHE and maven as part of the Liberty publishing tasks that run when a new version is released. We are looking to have this resolved with 22.0.0.2 which is scheduled to be available tomorrow if we don't run into any additional snags and the io.openliberty publishing goes well.

There is a very easy way of managing JDK installations almost automatically using something like SDKMAN. I suggest you have a look at this, as it would greatly simplify the process of managing whatever is that you need to manage. Note that the solution work for both MacOS and Linux.

QUESTION

TMC beans: The JDK is missing and is required to run some NetBeans modules

Asked 2021-Dec-01 at 07:28

I am new to programming and started the MOOC.FI course (https://www.mooc.fi/en/installation/netbeans) I am running Windows 10. I downloaded both TMC beans 1.4.0, as well as Eclipse Temurin JDK with Hotspot 11.0.12+7(x64).

When I open Netbeans, it says

The JDK is missing and is required to run some NetBeans modules Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJre for more information.

I tried :

Uninstalling and redownloading both the JDK and TMC beans.
Changing the tmcbeans.conf file, changing the file to: #jdkhome="C:\Program Files\Eclipse Foundation\jdk-11.0.12.7-hotspot"
Adding: netbeans_jkdhome="C:\Program Files\Eclipse Foundation\jdk-11.0.12.7-hotspot"

Both haven't stopped TMC Beans from returning the same message.

EDIT:

The problem is fixed, I downloaded OpenJDK 8 with hotspot from https://adoptopenjdk.net/archive.html?variant=openjdk11&jvmVariant=openj9

Then, I added the line 'jdkhome="C:\Program Files\Eclipse Foundation\jdk-8.0.302.8-hotspot"' to the tmcbeans.conf file. I found it at C:\Program Files\TMCBeans\etc.

After this, the message no longer appears.

After some checks on my system and other images I discovered that the "latest" tag of image "adoptopenjdk/openjdk11-openj9" is broken.

To fix the problem you can use a different tag (I switched to "adoptopenjdk/openjdk11-openj9:alpine" and it works). There's a similar bug for "adoptopenjdk/openjdk12-openj9" here https://github.com/AdoptOpenJDK/openjdk-docker/issues/194.

I've also open a bug for this problem here: https://github.com/AdoptOpenJDK/openjdk-docker/issues/610
