Dear Maintainer,


The invocation of epubcheck is  broken on my systems.

The error message is:

   /bin/epubcheck: line 1: $'PK\003\004': command not found
   /bin/epubcheck: line 8: syntax error near unexpected token `('
   /bin/epubcheck: line 8: `��&�'gs��g��ٚ��qمlT�D�E�
   ��PD<��������i��ѓa&�%                           .5(META-INF/maven/org.w3c/epubcheck/pom.xml�␦ks�6���W�����$;�5=�fkǏƩ7��nқ~��J�]ڒ�#)��L����c��&��� ���ϷIL��T\�/6���
   [...]


The jdk in use is:
   openjdk 25.0.4.1 2026-08-18 LTS
   OpenJDK Runtime Environment Temurin-25.0.4.1+1 (build 25.0.4.1+1-LTS)
   OpenJDK 64-Bit Server VM Temurin-25.0.4.1+1 (build 25.0.4.1+1-LTS, mixed mode, sharing)

I can mitigate the problem in 2 ways:
1. Calling it without *jarwrapper*: java -jar /usr/share/java/epubcheck.jar
2. Using *jarwrapper* 0.82 from forky.


I **can't* mitigate the problem:
- Using openjdk-25 from Debian trixie-security
    openjdk 25.0.4.1 2026-08-18
    OpenJDK Runtime Environment (build 25.0.4.1+1-1-deb13u1-Debian)
    OpenJDK 64-Bit Server VM (build 25.0.4.1+1-1-deb13u1-Debian, mixed mode, sharing)
- Removing both openjdk-25 and temurin-25installation and using openjdk-21 from trixie.
    openjdk 21.0.12.1 2026-08-18
    OpenJDK Runtime Environment (build 21.0.12.1+1-1-deb13u1-Debian)
    OpenJDK 64-Bit Server VM (build 21.0.12.1+1-1-deb13u1-Debian, mixed mode, sharing)


Suggestion:
Please backport javarwapper 0.82 from forky to trixie.
