JNI Error when running 4.7.19

[Lumilias]

Hey Phoenix09,

First of all, thanks for repackaging Filebot. I would have compiled it from source too (since rednoah basically screwed those using Windows Server) but I decided against it since finding your release.

Anyways, I get the following error when launching 4.7.19: Error: A JNI error has occurred, please check your installation and try again.

Have you checked that this version runs in your own testing? Also, I noticed in the merged commits that rednoah added support for Java 9. Does it maybe need to be repackaged under JDK 9?

Thanks again for doing this!

the problem is FileBot was changed to compile with Java 9.

java -jar FileBot_4.7.19.jar
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: net/filebot/Main has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

it works for me as I'm running Java 9. I'll revert it to Java 8 soon.

Thanks! I tried running the GUI with JRE 9 installed, but it popped up with a message saying it required a JRE 1.8.0 environment to run in. I've got no problem with moving to JRE 9 personally.

As Java 8 is still the recommended version I think switching back to 8 is the better option.

Also only the GUI runs with 9: https://github.com/Phoenix09/filebot/commit/a2662791d07fbe69b4e8f24b968f90c850e9ae60

Ah, now that you mention that, I installed both JRE 8 & JRE 9 to test this. Using the launcher.exe shortcut fails with that error, but launching it directly via java -jar does allow the GUI to run.

So if you switch it back to Java 8, would that GUI commit be reverted back to 8 as well?

It is not enough to install Java 9 / JRE 9, at least it wasn't enough for me, I had to modify the registry, somewhere here: HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment. I've added the 9.0.1 key similar to what existed to 1.8, with JavaHome and RuntimeLib.

After that, the Filebot launcher was able to understand that JRE9 is installed and everything started working fine.

@vvs Thanks for the tip! I did the same and it works again.

Attached relevant registry file which adds required keys to registry. It needs java 9.0.4 installed under C:\Program Files\Java\jre-9.0.4 but the file can be edited manually to work with other versions installed under different locations.

Original Java installer creates these keys under HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JRE instead of HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment which confuses filebot.launcher.exe

this should be fixed with the latest release
