Re: [Ikvm-developers] More RXTX

[Jeroen F. <je...@su...>]

This looks like an RXTX bug. It tries to read a long field with GetIntField.

In SerialImp.c:

struct event_info_struct *eis = ( struct event_info_struct * ) get_java_var( env, jobj, "eis", "J" );

This passes in "J" (the signature of a long field), but the get_java_var function always uses:

result = (int)( (*env)->GetIntField( env, jobj, jfd ) );

to read the field.

Jeroen
