Zdravim,

ako sa da, prosim, overit, ci sa pouziva Stub alebo nie? (je tam pritomny,
nazvany defaultne od rmic, ovela viac neviem - strace mi na JVM nefunguje)

Totiz, iste nastavenie mi hadze StackOverflowError (v prilohe) a tipujem to
na chybu v Set-e - ako sa ukazovalo na prednaske, ze pri nepouzivani Stubu
nemusi ani .equals() fungovat tak, ako by si clovek predstavoval.
Mozno mam chybu aj inde, ale to zo stacktrace nevidim.


Dakujem za prip. hinty, kde moze byt chyba al. riesenia problemu so Stubom,
Peter Junos
