the only java sdk that is not giving me this error with the password ( java.io.IOException: DerInputStream.getLength()...) is JDK 1.8.0_112 see Link
So if I put this version of java sdk (8u112) in Flash Builder I can create an apk build that will upload to Google Play, any other way will not work, not even taking my old password and converting it with 112 jdk to keystore file and try to register the apk file with a new keystore with jdk 8u321.
I still get the same error.
I don't mind working with java sdk 112, I can build an apk file even with my old password with this sdk, but when I upload the file to Google Play it still says that in a few months I will not be able to upload files that don't support 64 bit, is that a problem with the sdk? or with AIR sdk 33? or with Flash Builder? how do I produce a 64 bit apk with Flash Builder 4.7?
