these are lines that produced it

 private inetaddress as JavaObject
.....
.....
    'works
    Log(inetaddress.InitializeStatic("java.net.InetAddress").RunMethodJO("getByName",Array As String("www.hjhkahkd.co.uk")).RunMethodJO("isReachable",Array As Object(2000)))
    'strange error
    If inetaddress.InitializeStatic("java.net.InetAddress").RunMethodJO("getByName",Array As String("www.hjhkahkd.co.uk")).RunMethodJO("isReachable",Array As Object(2000)) Then
        Log("reachable")
    Else
        Log("unreachable")
    End If

In java terms the object Boolean is different to the primitive 'boolean'.

What happens if you do:

Dim B As Boolean
B = inetaddress.InitializeStatic("java.net.InetAddress").RunMethodJO("getByName",ArrayAsString("www.hjhkahkd.co.uk")).RunMethodJO("isReachable",ArrayAsObject(2000))

If B Then
Log("reachable")
. etc.

It failed, I've checked, you'll need to do something like:

 If inetaddress.RunMethodJO("getByName",Array As String("www.hjhkahkd.co.uk")).RunMethodJO("isReachable",Array As Object(2000)).RunMethod("booleanValue",Null) Then

 

[Daestrum]

its odd that

......RunMethod("booleanValue",Null)

works as expected but

......RunMethodJO("booleanValue",Null)

still produces the error

 

[stevel05]

It's getting late!

If inetaddress.RunMethodJO("getByName",Array As String("www.hjhkahkd.co.uk")).RunMethod("isReachable",Array As Object(2000)) Then

works too.

RunmethodJO returns a JavaObject containing the value whereas Runmethod returns the value.
