« on: July 09, 2021, 10:04:53 PM »

Hi,

downloaded JPPF-6.2-Web-Installer.jar from https://jppf.org/downloads.php
run java -jar JPPF-6.2-Web-Installer.jar (on windows 10 workstation)
will open the JPPF Installation Wizard, hit next, accept license agreement, select installation path, hit ok , create the file in D:\temp\jppf62\izWrTe7103924964133648357.tmp
Pack installation progress --> finished
Overall Installation progress --> 6/6
see PDF attachment
and receive an Error window with the message Installation failed
exactly same behavior with JPPF-6.1.4-Web-Installer.jar

Anyone who made the same experience and found a solution?
Any support appreciated
thanks in advance

Hello,

I was able to reproduce this behavior once, but only with Java 15. I had no issue with Java 8, 11 or 13. After killing the java process the first time, the error never happened again. However, I could capture the following error message:

Code: [Select]
C:\Temp>C:\java\jdk-15.0.2\bin\java -jar JPPF-6.2-Web-Installer.jar
java.lang.NullPointerException: Cannot invoke "java.io.InputStream.read(byte[])" because "<local5>" is null while trying to download https://www.jppf.org/download/6.2/JPPF-6.2-Web-Installer.pack-JPPF_Driver.jar

I will keep inivestigating and provide a status with my findings.

Sincerely,
-Laurent

Hi Laurent,

thanks for the quick update
fyi I received the message using  Java 8 + 12 (w2k12/Windows 10).
Sincerely
Denzel
