R did not generate REngineEvalException on RTest

[AlexBurdu]

I am testing JRI using the RTest class in the org.rosuda.REngine.JRI.test package and I am getting the following error:

    rnorm(5); stop('error'); rnorm(2)Error: error
    Exception: org.rosuda.REngine.JRI.test.TestException: error in R did not generate REngineEvalException
    org.rosuda.REngine.JRI.test.TestException: error in R did not generate REngineEvalException at org.rosuda.REngine.JRI.test.RTest.main(RTest.java:283)

I tried to trace the error into the JRIEngine object and rni.Parse(text, -1) returns 139793149998072 and is compared with R_NilValue = 139793132433096 and 0 in order to check if it throws a REngineException. I don't know what 139793149998072 means and how to fix this. Any hints?

Sorry, you'll have to provide a bit more detail - the test works just fine for me. Please provide full sesionInfo(), your OS version, Java version and how you started the test.

Also the point you're pointing to has nothing to do with it - the parse step won't fail in that test so it's correct that the reference is different from both null and R_NilValue.

I'm just running the RTest.java class from netbeans to test the environment. Here's the output:

Thanks, this is a different test than what I thought you're using (I assumed JRI while this is actually in REngine). Yes, I can replicate it now. Instead of throwing an exception it returns NULL, I'm looking into this.
