Ciao a tutti!
Sto creando una classe in java che utilizza codice nativo C, attraverso una dll che ho creato, solo che quando eseguo uno dei metodi della classe, mi da il seguente errore:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x18062366, pid=1100, tid=5572

Il metodo in questione sta utilizzando le librerie del driver generico WinUSB della microsoft che si può trovare nel pacchetto "windows driver kit", per gestire un dispositivo USB. In particolare questo metodo invia dei SET UP TOKEN all'endpoint 0.
Se lo stesso metodo lo eseguo direttamente da un compilatore C++ funziona perfettamente.
Qualcuno ha qualche idea di come posso risolvere il problema???
Ecco anche il contenuto del file "hs_err_pid1100.log" che riporta l'errore in dettaglio:
