I am currently working on a project where in three location the timezones are coming incorrectly.I tried updating my tzmappings file from jre 1.8 .In this process I could able to see the correct time in one location and other location time are still wrong.We embedded the jre with our application and for that we were using jre 1.6.I understand upgrading to new jre i.e jre 1.6->Jre1.8 will be solve this problem.But let me know if anything apart from this i can do to resolve this.
Update: Tried running TZupdater but ends up getting NPE detail stack trace below

Our application uses Tomcat v9.0.41 and JDK 1.8.0_111 . This same combination works for others in my team and also it worked for me sometime back. I'm not sure what changed now. I have looked at other similar posts and they suggest mismatch between Tomcat and JDK version. But above combination of Tomcat and JDK works for others.
I have removed all other JDK and JRE version on my system.
Ensured JAVA_HOME points to JDK 1.8.0_111 and PATH points to correct JRE.
Any pointers on how to debug this further? Can I turn on some logging during Tomcat startup to see what paths are being used by Tomcat? Any suggestions are highly appreciated :).
Using journey browser project I have set up a simple maven project in eclipse, using the dependency provided on the page, I have tried to run the code example (also provided on the page)

Can anyone explain what is happening and why here, I have tried this on 64bit windows with java Coretto 11(jdk11.0.7_10),I initially found a bug here, relating to loadLibray in open JDK and thought that maybe the problem, I just don't have a good enough understanding to work out how to get around it?
I'm not sure, but I think that Corretto bug is probably the one that is causing the problem. As noted, it is from their "upstream"; i.e the OpenJDK codebase. It was due to regression that appeared in jdk11.0.7 due to a backport of a fix for another problem. Apparently, the fix changes some internal JDK fields and that breaks application code. As JDK-8240521 puts it:
The backport of the JDK-8231584 changes internal JDK fields processing. The problem is that the many third-party applications copy-pasted a hack that depends on particular JDK implementation.
If I am reading the Oracle bug entries correctly, the reversion of the broken fix should be in JDK11.0.8. Alternatively, an earlier JDK 11 release than 11.0.7 shouldn't have the broken fix.
Let me know if changing your Java 11 install solves the problem. (If not, I'll see if I can get the line numbers to match up.)

I check my java's versions to see if I have a bad/old one, but all is on date :
JDK 13.0.1
JRE 1.8.0_241
JavaFX 11.0.2
I found answers on this forum but none helped me. :
Write java -jar filename.jar in a .bat file and execute it.
Extract the folder and try to run it.
Place jdk-13.0.1\bin and Java\jre1.8.0_241\bin above the Common_Files\Oracle\Java\javapath (I deleted it finally, it was the easiest way to try to fix my problem).
If anyone here thinks they can help me, tell me! :)
Okay, after hours spent fixing my problem, I finally found it for myself!
For all those who have the same problem, follow what I will say:
There must be ONLY one version of Java on your pc (wether it's the JDK or JRE). So, only keep the java version you want and try to compile your file with java -jar fileName.jar and it should work.
I myself had the JDK and the JRE, both added to the path of the environment variables. So the error came from here.
The only thing I don't understand is why the JRE created a problem during the execution when I had put the path of the JDK above.
I got this error message in the console when I tried to run, I just switched laptops and I've wiped my old one. This project has always been stored in a USB so I use that to run it on my new laptop. (So I had to re-download all the applications), I need this to fix so bad due to its my project for class and I haven't record it and I'm supposed to do that and I don't want to fail the class please could u help thank u:

I at first download JDK 10 and I read it only works with JDK 8 so I download that and delete JDK 10 in hopes that stuff will return back to normal and it does not works. Also the project, I did it in java oxygen and I downloaded photon on my new laptop and click on the yes I want to convert the files thing so I decided to make a new workspace and copy paste the code but still got that error?Before it was MacBook Air and I switch to the MacBook Pro.
You are mixing up a lot of things.
The basic problem is that starting with Java 9 oracle made changes that lead to such errors ( see https://docs.oracle.com/javase/9/migrate/toc.htm#JSMIG-GUID-C86F7403-7D7C-456F-8873-18C7F1BEDE2F).
So, in order to get this to work, you have to ensure that Java 8 is used. And that your Java 10 installation was really, fully removed. You should then check your eclipse settings to also ensure that it is pointing to Java 8.
I wrote a program that uses the VirtualMachine attach API to dynamically attach to a jar. My machine is 64 bit, and the only reason I can think of that would stop is because of my messing around with the environment variables of java(no java_home was set and I tried to fix it). Since getting this error, I have reinstalled both the JDK and JRE to no avail. My guess is that it is some sort of problem loading attach.dll, which is 64 bit.
Anyone have suggestions?
