I'm trying to get classes from JAR file / actually running JVM machine but:
When I'm trying to open JAR file using for example 7Zip I dont see any classes. After unzip Manifest file is empty too.
When I'm trying to "dump" classes from running JVM machine, I got "very funny" named - empty classes (not really empty, but contains info like "gtfo" etc..)
JD-Gui showed nothing - just nothing.
Around month ago, when I tried to open it using 7Zip, there was classes with same name, and custom extension.
What should I do, and what tools do You recommend for actions like this?
EDIT: Every decompiler I tested show info like this:
mv.visitMethodInsn(INVOKESTATIC, "net/minecraft/client/main/Main", "\u0000extends throws try goto 8 \n 9 * package * + finally return static * " float abstract | transient \n synchronized catch = strictfp transient static extends while final long ! 0 throws & \n % double 4 this if const \n interface ' ^ ~ do 1 ] % ? throws super long", "(Ljava/lang/String;)Ljava/lang/String;", false)
