method in converted class has illegal modifiers: 0xA #23
Description
dex2jar successfully converts the classes in my apk to a jar file.
However, while attempting to inspect those classes in a desktop application with Class.forName(name, false) (note the initialize = false arg), I see this error:
error: unable to process AboutBottomSheet.kt: Method $jacocoInit in class androidx/lifecycle/HasDefaultViewModelProviderFactory has illegal modifiers: 0xA
After some investigating, I'm guessing this corresponds to a default modifier in the HasDefaultViewModelProviderFactory interface (defined by Android):
default CreationExtras getDefaultViewModelCreationExtras() {
return CreationExtras.Empty.INSTANCE;
}
This modifier was introduced in Java 8 (52), but the Android classes are for Java 6 (50).
So I believe the error results from a newer modifier in an older class version where it was not supported.
Can someone with greater knowledge confirm this suspicion, or comment on what else might be going on?
Incidentally, I tried converting that class to level 52 with d2j-class-version-switch.sh, but the problem remains.
