Can you attach sources of your project? At least HestonProcessChart would be interesting. Also please check if there were any errors reported in the log of the IDE during compilation .

Sure thing, expect a link shortly, it requires swig and flint-arb for a native library to be built

11 months ago Hello @iloveeclipse , I appreciate your patience, the code can be found at
https://github.com/crowlogic/arb4j
I just verified the issue is still happening. You might find the library fun, it's becoming quite useful

I checked eclipse logs.. nothing related to compiler

Exception running application arb.stochastic.volatility.heston.HestonProcessChart@crowlogic : thanks. May I ask you try with latest nightly build of Eclipse (https://download.eclipse.org/eclipse/downloads/drops4/I20230806-1800/)?
Other remark: this project uses m2e to resolve dependencies and also CDT to build which requires to install those for reproducing.
Is there a way to get a stripped down self contained project or java code that would show the problem in a plain SDK?

I can upload the .so then you can just disable or ignore the cdt part. I'm not sure about other platforms

If you instruct me how to generate a standalone lib directory...

Sorry that you seem to be blocked here - but you first submitted this on Saturday evening and have gotten lots of response already.

Try using javap to see the difference in class files. With -c it disassembles the code.

11 months ago My hunch was right that it was getting confused by having a class named arb.arb , i renamed the swig module to arblib so that mapping is arb.arblib and everything works great. there isn't sufficient incentive to investigate further, thanks --StΣvε
I figured this out because if I clean and rebuild outside of eclipse with maven, all is well,
the thing is, arb.stochastic is a packaeg name I've no idea why it would be trying to load it as a class..
heres my directory structure of the project..

how can i remedy this or figure out what's causing it?
