Hi,
I have developped a java swing application (1.6) embedding R (using the 
JRI, JRengine) and all was fine on my previous laptop (Mac OS X Leopard, 
10.5).

But I had to change my laptop (Snow Leopard 10.6.4, 32 bits with java 
1.6), and now there is a failure, which seems to come from cocoa (read 
this on other forums). The error "__NSAutoreleaseNoPool" is on all 
forums.//For instance, see
http://www.omnigroup.com/mailman/archive/macosx-dev/2001-July/029778.html/
/
I use the R  binairies downloaded from CRAN :
http://cran.r-project.org/
I also have installed the Xcode SDK

Here is my stack trace :

Ok all is fine
But ...

Reading this post, 
https://stat.ethz.ch/pipermail/r-sig-mac/2010-December/007913.html, I 
understood that

/"the latest update to Snow Leopard (10.6.5) removes necessary header/  /files from the system Java installation."
/

OK, and all this have been ennoying other people using the mac OS X JVM 
for other applications.
/
/
So I have followed the advice : installed the Xcode SDK and made java 
reconf for R with good CPP flags/

Done.

Unfortunatly, the problem is going on...

Have you any idea ?

Here is the command to launch my application.
java -d32 
-Djava.library.path=/Library/Frameworks/R.framework/Resources/library/rJava/jri 
-cp "${ESTIM_DIR}/lib/JRI.jar:${ESTIM_DIR}/lib/JRIEngine.jar --arch 
i386:${ESTIM_DIR}/lib/postgis_1_0_0.jar:${ESTIM_DIR}/lib/postgresql-8.1-404.jdbc3.jar:${ESTIM_DIR}/lib/REngine.jar:${ESTIM_DIR}/dist/ESTIM.jar" 
Estim

Thanks in advance,
Christine
