Last week I pushed out an enhancement to ToastBar that changed the static showMessage methods. I made them return the Status object instead of void which would allow more control of the toast message after it’s shown. Unfortunately, I totally forgot that I can’t do that without breaking some binary compatibility.
In Java return types create a distinct method signature, so even though the language doesn’t allow you to do this:
void myMethod() {
}
int myMethod() {
return 1;
}This is actually valid in the bytecode level. Furthermore, it’s a used by the JVM to implement Java language features like covariant return types.
So if you used ToastBar and compiled against older libraries you might experience issues when building. Make sure to update your client libraries before sending a build by going into Codename One Settings → Basic → Update Client Libs. Then do a clean/build before sending a new build.
