    The version was the latest aka the default.

    openjdk 11.

    But the fix is simple - 
    1. Open a Terminal
    2. run Java --version and note your version

    3. run sudo update-alternatives --config java

    4. select the openjdk 8 and test.

     

    You may have to try a couple of versions, depending on the age of your system.

    What is the java version used while invoking the tool. Looks like you are using lower version of java.

      Hi btolman,

       

      nmrao is right, you got troubles with your java version.

      For information:

      • SoapUI 5.5 --> JRE 8
      • SoapUI 5.6 --> JRE 12

      If you install SoapUI with the installer, the JRE is included (in my case on Windows, don't know for other distributions).

      If you just copied files or renamed the JRE folder, you might have this kind of trouble.

      Can you check both java version installed on you machine and the one used by SoapUI ?

       

      Let us know.

       

       

      David.
