I have just made the BIG mistake of accepting to install the upgrade on Soap UI.
My previous version was Soap UI 5.5.0 and I had Java 8.181 installed and everything was fine...
Then, I still don't understand why, when I lauched my Soap UI, I've accepted to take the update...
Then I got the exaclty same error message (printed herewith by the way) after the installation.
Despite that Java is not anymore around version 52 or 53, but more like 7 or 8, I have understood that I needed to update also my Java Runtime.
What I have done by installing the latest Java version --> 8.261
Then, I still got the same error message...
After, I was thinking that I may be need to restart my PC, what I've done full of hope (I must even say, last hope)...
And guess what ?
Still the same error message when I lauch Soap UI !
That is why I'm here, can you please help me ?
It is really urgent I must say.
After a lot of Internet browsing and reading, I fixed the problem by installing Java SE 14 found on the page https://www.oracle.com/java/technologies/javase-downloads.html after clicking the link JDK Download.
It then tooks me to the page https://www.oracle.com/java/technologies/javase-jdk14-downloads.html where I downloaded the version I needed. Windows 10 for me so I picked up the jdk-14.0.2_windows-x64_bin.exe
And now, I can finally launch my Soap UI 5.6.0 successfully.
Thanks ✌️ 👌
