I'm facing problems with Oracle SQLDeveloper and I don't know how to solve this.
I installed JDK 18 in my Ubuntu 22.04 and each time I try to open SQLDeveloper I got this error.
java.lang.Error: no ComponentUI class for: oracle.ide.controls.StatusBarControl$JDevStatusBar[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,border=,flags=0,maximumSize=,minimumSize=,preferredSize=]

I already tried to reinstall SQLDeveloper and JDK 18 too. Nothing changed!
I have a problem using AndroidStudio. I freshly installed it on my Kubuntu 18.04 machine and wanted to create my frist project. Everyhting worked fine and the project opened. The only problem: I can't run my apps. I can't even look at the activities in the design view - It waits forever for the build to finish. When I want to run the apps, it doesn't have any modules.
After searching for a while on the web I tried syncing my project with the gradle files, because that seems to resolve similar issues, but once I do that, the following error occurs:
Argument for #NotNull parameter 'message' of com/android/tools/idea/gradle/project/sync/GradleSyncState.syncFailed must not be null

After doing it once, the button for syncing is disabled and I can't do it again. I have to restart the IDE to do that.
I looked into the idea.log file to better track down the issue and I found the following there:

It seems like the project can't be synced to my gradle files. Probably the actual problem of running my app is based upon this one. Has anyone had this issue before or can help me by telling me how to tackle this?
I am completely new to AndroidStudio and also to Gradle.
Ok, I was finally able to figure out the reason.
The problem was, that my project folder resided on a different hard disk partition, than my home folder. The folder containing my android projects was linked to my home folder with a symbolic link.
I can't tell whether its the symbolic link, or the other partition, that is causing the problem. I haven't checked that. Maybe it works if you have it on the same partition but linked with a symbolic link. Maybe it works when used on another partition without symbolic links. But for anyone experiencing this problem -> Check if one of these might be your cause as well.
Some extra information: My android project folder resided on a hard disk partition formatted with ZFS.
I saw a version of this with just now on Android Studio 3.4: the only error message I saw in the IDE was that Gradle sync failed, but in idea.log there was a NullPointerException and its traceback originated at com.intellij.openapi.extensions.Extensions.disposeArea and was just like the one in the question.
The fix that worked for me:
rm .idea/modules.xml
Then try Gradle sync again.
This also caused that file to get automatically regenerated. The new version had exactly the same entries as the old, plus some additional ones for various library dependencies. Not sure if those entries being absent was the cause of the issue, or an unrelated accident.
Before that, I tried "Invalidate Caches / Restart...", and it didn't work in my case. Also double-checked and there are no symbolic links in my project path, or the paths to Android Studio or the Android SDK.
Had a similar problem after renaming the project folder and adding the renamed folder as new project.
solved this by the infamous "Invalidate Caches / Restart" option
(before I removed the old project link which was not enough)
check this :
Argument for #NotNull parameter 'module' of com/intellij/openapi/roots/ModuleRootManager.getInstance must not be null
by the way , i usually delete .idea and .gradle folders inside my project folder after updating android studio , almost works for all new bugs after updating .
Faced same issue, wasted a day reinstalling everything and figured out just now. It happens if you create a symbolic link to your project and specify the path through that symbolic link. Just specify the project path by going the long way and everything will work just fine.
I had the same problem. I move the ~/Android/Sdk folder to a different partition and placed a symbolic link!!!
Solution for me:
Delete .android , .AndroidStudio3.2 , .gradle folders
Start studio.sh again and let it initialize things as for the first time. Then go to File->settings->System Settings->Android SDK and give the new location to the Android SDK folder as an absolute path (not symbolic links).
After this, it worked like charm.
I solved the problem by rename the project folder and then reopen android studio , android studio will tell you that it can not find the project , then remove the project from the android studio current open list . rename project folder back and open it by android studio again .
I got same issue in Android Studio 3.4.
I managed to fix it by restoring my previously deleted app-name.iml file.
I also had the same problem and simply resolved it by closing android studio, deleting .idea and .gradle files located on the project folder and then reopening android studio.
I have a JaCaMo project where I'd like to stop the system when a believe is added as follow:
+winner <- .stopMAS.
I am doing like this in a pure Jason project, but in this JaCaMo project where I have an organization, after this stopMAS command an error is ocurring in CArtAgO API as bellow:

How to avoid this error? Is there anything I should do before this stopMAS command?
You can just ignore this message. The latest version of JaCaMo (0.7-SNAPSHOT) fixes this problem.
I am trying to upgrade a Cassandra 2.1.0 cluster to 2.1.8 (latest release).
When I start a first node with 2.1.8 runtime, I get an error and the node refuses to start.
This is the error's stack trace :

The cluster has 7 nodes and it turns on AWS Linux EC2 instances.
The node I try to upgrade was stopped after a nodetool drain.
Then I tried to come back to 2.1.0 runtime but I now get a similar error.
I also tried to stop and start another node and everything was ok, the node restarted without any problem.
I tried to touch the missing file (as it should be removed, I thought it would perhaps not need a specific content). I had two other files with the same error that I also touched. And finally the node fails further while trying to read these files.
Anyone has any idea what I should do ?
Thank you for any help.
It might be worth opening a Jira for that issue, so if nothing else, they can catch the NPE and provide a better error message.
It looks like it's trying to open:
file: /home/nudgeca2/datas/data/main/segment-97b5ba00571011e49a928bffe429b6b5/main-segment-ka-15432-Statistics.db
It's possible that it's trying to read that file because it finds the associated data file: (/home/nudgeca2/datas/data/main/segment-97b5ba00571011e49a928bffe429b6b5/main-segment-ka-15432-Data.db). Does that data file exist? I'd be tempted to move it out of the way, and see if it starts properly.
