HIDDemo2 - JNI call ThrowNew failed to throw exception !

[Stephan Raible]

Hi RishiGupta12

I was just testing your new version of sp-usb with the HIDDemo2 application. As soon as I unplug my MCP2200 USB HID device my output log in Netbeans quickly fills up with the following error messages:

1. JNI call ThrowNew failed to throw exception ! , FormatMessageA() , error code : 15100
2. JNI call ThrowNew failed to throw exception ! , FormatMessageA() , error code : 15105

The second message repeats infinit and my CPU usage of one core goes up to 100%.

Any idea what went wrong here? Since I can't check the dll's myselve I have no options here to look into the details.

Thank you very much in advance for your help.

Kind regards,

Stephan

Hi, Sorry for delay. I have been overloaded with other works. I tested latest release with mcp2200 and it seems to work fine. Please tell me:

- which version of windows you are using

- how exactly application uses serialpundit api

- is your app UI based or does not have UI.

- your timezone and country

I have updated the jar file. Please use latest sp-hid.jar file, latest demo app and hid api.
