Description
What version of Go are you using
go version devel +c7eb966 Wed Dec 24 07:30:28 2014 +0000 darwin/amd64
What operating system and processor architecture are you using?
osx 10.9.5 cross compiled for arm on Android 5.0.1 Nexus 5
What did you do?
Tried to call a go function from java that takes a byte[] and a string. The inverse go to java call has the same issue. If the byte[] is preceded by an int, it behaves normally.
What did you expect to see?
fmt.Printf to get called
What did you see instead?
Application crash, no error messages generated.
To reproduce, modify the libhello example by adding these functions
// This ordering of the parameters works
func OkFunc(someBytes []byte, str string) {
fmt.Printf("Got a string %s and some bytes %v!\n", str, someBytes)
}
// This ordering causes a crash
func CrashFunc(str string, someBytes []byte) {
fmt.Printf("Got a string %s and some bytes %v!\n", str, someBytes)
}run gobind, then back in java add this after the initialization
// create a byte array, size/content isn't important
byte[] bytes = new byte[1024];
for(int i=0;i < bytes.length; i++){
bytes[i] = 8;
}
// This one works
Hi.OkFunc(bytes, "stuff");
// This one crashes
Hi.CrashFunc("stuff", bytes);
