I'm trying to read a file that was created using Java's ObjectOutputStream. I simply replaced "ObjectInputStream" with "FSTObjectInput", but it throws the error above.

JDK: 1.8.0_65 OS: Windows 7

RuedigerMoeller commented 7 years ago

fst is not binary compatible, but "source-compatible". You cannot read files created with jdk serialization

Ah I see, I will convert the files then from JDK serialization -> FST serialization. Thanks
