ZipException while opening Jar #539

Closed MrExplode closed 4 years ago

MrExplode commented 4 years ago

SO I tried to open a jar to remove further obfuscations, but I got this exception. I have to note that this Jar is a repackaged jar, because it was encrypted with various methods before, so I decryptied the files, unzipped the whole jar, then repackaged with this code I wrote.

On jdk 8 it gives an other error: java.util.zip.ZipException: error in opening zip file

Java version: AdoptOpenJDK 11.0.6.10

java.util.zip.ZipException: zip END header not found

Update: I installed OracleJRE 8 and tested it with various other jar files, but the error still happened.

I feel like this error is likely not inside java-deobfuscator.

Found the problem, wasn't related to java-deobfuscator.
