    As some methods/classes are not available in older versions of Java, I have started checking the version installed in my libraries. The code is simple to add to the initialisation routine of the library.
    Public Sub Initialize
    Dim ver As String = GetSystemProperty("java.version","0.0")
    If ver.StartsWith("1.8") = False Then
    Log("Sorry ????? library requires Java 8")
    End If
        ... rest of initialisation ...
    End Sub
    Saves you having to answer questions as to why it doesn't work, when run on older versions.
    jmon and Erel like this.
