Hello Sylvain,

if an internal error occurs in GLPK for Java it calls glp_free_env() before throwing GlpkException. This frees (and invalidates) all memory allocated by the GLPK library.

The exception will not free memory allocated by
- new_doubleArray
- new_intArray

For these you have to call the delete methods
- delete_doubleArray
- delete_intArray.

Garbage collection will neither free said arrays nor any memory assigned by the GLPK library.

Best regards

Heinrich Schuchardt

Hello Heinrich,

Rabih talked about garbage collection. I'd like to know if GLPK for Java
handles garbage collection and automatically deletes the problem object
in C (either in case of exception or in a normal run) or if it must be
done by hand.
If GLPK for Java handles garbage collection, could you tell me since
which version?
