problem with workflows using Rexpression on Windows XP
On Windows XP workflows using RExpression don't finish execution. This happens in RC2 and wrp trunk on XP, the console for wrp trunk endlessly spews:
WARN (org.ecoinformatics.seek.R.Rxpression$_StreamReaderThread:_read: 1615) In catch block of _read!

I found two workflows can not be executed on Windows 7 64 bit: Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\R\localFile_to_dataFrame_R and sampling_occurrenceData_ R.
First of all, many workflows still use property("KEPLER") which should be changed to property("DEMODIR").
For workflow "sampling_occurrenceData_ R", it tried to use property("KEPLER")+"/lib/testdata/garp/DataPoints.txt". I finally found the file at Kepler-2.0.0-Demos\demos\R\data\garp directory. So it probably should be property("DEMODIR")+"/data/garp/DataPoints.txt"
After I manually pointed to the correct dir, these two workflows work for me.
I also tried workflows in Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\JRI directory, the whole Kepler just quit with the following message in the console. It makes sense that the dll doesn't work for 64 bit machine. But just quitting Kepler is too unfriendly.

P.S.: Do the workflows in Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\JRI\problems directory really have execution "problems"? This directory name is confusing.

1. Derik will change the workflows to point to the DEMODIR path.
2. The RExpression2 (JRI-based) actor will fail if the libs are not found. This is probably deep in the JRI.jar library when it cannot load the correct native lib for the platform. We could probably try to detect the 32 v. 64 bitness of the system and prevent the actor from attempting to use JRI if it was on a 64 bit machine - otherwise it will be the hard failure (system.exit)
3. the JRI/problems directory contains workflows in which I swapped the original RExpression actor for the RExpression2 actor to see if they were compatible. These workflows showed slight differences and require changes in order to run. The specifics are captured in another bug (http://bugzilla.ecoinformatics.org/show_bug.cgi?id=4010)

Matlab actors also have 32 and 64 bit issue when using JNI libraries to communicate with Matlab. It will pop up an exception message when the JNI lib doesn't work with the system. You can find some information at https://kepler-project.org/developers/teams/build/matlab-lib-build-instructions-in-kepler-for-matlab-actor. It may help this bug.
