B4J Question class java.lang.Error cannot be cast to class java.lang.Exception ?

[tchart]

I have a try/catch block in a B4J project.

In the catch code Im just using this; Log(LastException)

But this is causing an exception of its own and the app is crashing. In the logs is the following;

Caused by: java.lang.ClassCastException: class java.lang.Error cannot be cast to class java.lang.Exception (java.lang.Error and java.lang.Exception are in module java.base of loader 'bootstrap')

Any idea why Log(LastException) isnt working in this case?

Where does the Error come from? Such errors are not meant to be caught.

Erel, Im not 100% sure. Im using a library method to retrieve server process information on a timer, I believe its this method that is causing the error but this is kind of expected as the information Im retrieving may not be there on every tick (i.e a process may have been terminated).

I was mainly curious why it was returning an Error instead of an Exception.

For now Ive commented out the Log(LastException) line and I will monitor to see how it behaves now.
