I just noticed org.netbeans.modules.nativeexecution.api.util.PasswordManager via Encrypter (due to warnings during compilation about sun.misc.BASE64Decoder). While I'm not sure exactly what this is for, it looks like it is storing passwords in the user directory. If so, please use the new Keyring API for such purposes.
fixed, change set:
BTW you may wish to read and convert passwords saved in the old system, for a smoother transition for users importing their old settings.
Integrated into 'main-golden', will be available in build *201002040200* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
