Are there any plans to support BBMD in BACnet4J?

Thanks.

Matthew,

I'm getting an exception in seroUtils.jar. Near as I can tell it occurs when there are multiple concurrent requests for values for several different slaves. The exception stack is:

java.io.IOException: Stream closed.
at java.net.PlainSocketImpl.available(PlainSocketImpl.java:434)
at java.net.SocketInputStream.available(SocketInputStream.java:217)
at java.io.BufferedInputStream.available(BufferedInputStream.java:381)
at com.serotonin.io.InputStreamListener.run(InputStreamListener.java:67)

The only way it appears I can correct the problem is to restart the application and everything will work fine so long as I don't hammer the requests concurrently.

Have you seen this before?

The version of Modbus4J is 1.02.

Regards,
Fred

Matthew,

Can you tell me what prompted you to change the licensing for Bacnet4J and Modbus4J from LGPL to GPL v3?

Is there another way these products can be licensed other than GPL v3?

Thanks Matthew,

I did the build myself for the update you checked in for SequenceOf.java since I didn't see an updated jar file. The rest of my code is relative to the latest release published on sourceforge.

If I can avoid it, I never like building 3rd party libraries.

Fred

Fred

Thanks Matthew, that did the trick.

Can you share your plans on when you'll be updating the released versions of bacnet4j and modbus4j?

Regards.

Matthew,

I've been doing a bit of testing and I hit a NPE in SequenceOf.java.

Here's a little background:

I give my user the ability to add/remove sensors (analog or binary inputs) they want exposed through BACnet. So let's say I create 10 bacnet objects I add to my local device. Everything is fine. I hit my slave server with a BACnet browser and I can see everything as expected. If I delete any number of bacnet objects using removeObject on the local device and then run the scan again from my BACnet browser, I get the exception.

Here is the full stack trace:

java.lang.NullPointerException
