Python using Tabula / Java unsupported ClassVersion?

i try to use the tabula-module with python and have this code:

import tabula file = "input.pdf" tables = tabula.read_pdf(file, pages = "all", multiple_tables = True) 

When i try to run this code on windows i get this error:

$ python exampleTabula.py Error from tabula-java: java.lang.UnsupportedClassVersionError: technology/tabula/CommandLineApp : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) Exception in thread "main" Traceback (most recent call last): File "C:\DEV\Python-Diverses\PDFExtract\exampleTabula.py", line 3, in <module> tables = tabula.read_pdf(file, pages = "all", multiple_tables = True) File "C:\DEV\.venv\Normal\lib\site-packages\tabula\io.py", line 322, in read_pdf output = _run(java_options, kwargs, path, encoding) File "C:\DEV\.venv\Normal\lib\site-packages\tabula\io.py", line 80, in _run result = subprocess.run( File "C:\Users\WRSPOL\AppData\Local\Programs\Python\Python39\lib\subprocess.py", line 528, in run subprocess.CalledProcessError: Command '['java', '-Dfile.encoding=UTF8', '-jar', 'C:\\DEV\\.venv\\Normal\\lib\\site-packages\\tabula\\tabula-1.0.5-jar-with-dependencies.jar', '--pages', 'all', '--guess', '--format', 'JSON', 'foo.pdf']' returned non-zero exit status 1. 

I checked the java-installation an get this infos:

$ which java /c/Windows/system32/java 

and

$ java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode) 

What i have to do to use tabula on this configuration?
