Bug:Cannot read smart meter after exporting code (RXTX problems)

[JamesPiggott]

After exporting fpai-apps and starting it with the ./start script the flexiblepower.driver.smartmeter module does not connect to the meter. It only works when I use Ubuntu in VMware (my development environment) but not on my Beaglebone Black which I tested with Ubuntu, Debian and Red Hat. The problem may be due to the RXTX drivers. Despite repeating the same installation procedures the problem persists. Reading the smart meters works with the cu command.

Smart meter data is expected to be read by SmartMeterDriverImpl
This does work when I start the application in Eclipse.

A sample of the error output can be seen below.

It's highly recommended that you fix the library with 'execstack -c ', or link it with '-z noexecstack'.

SmartMeterDriverImpl.java has been adjusted to also accept data packets from the Landis and Gyr E350 which has a different communication protocol. However reverting back to an old version of fpai-apps did not help. This problem centers solely around the RXTX libraries.

A potential work around is using Python or Shell to read the raw data packets and use the remaining code of flexiblepower.driver.smartmeter to create power consumption format. Not my preferred solution for now
