Bug#943662: libproguard-java: Does not support Java 11, the current default jdk

[Timo Kalliomäki]

Package: libproguard-java
Version: 6.0.3-1
Severity: important

Dear Maintainer,

the currently packaged version of proguard (6.0) is incompatible with the
currently packaged version of Java (11). Trying to run proguard with he 
option

   -libraryjars 
/usr/lib/jvm/java-11-openjdk-amd64/jmods/java.base.jmod(!**.jar;!module-info.class)

will output the following error:
   Reading library jmod 
[/usr/lib/jvm/java-11-openjdk-amd64/jmods/java.base.jmod] (filtered)
   Error: Can't read 
[/usr/lib/jvm/java-11-openjdk-amd64/jmods/java.base.jmod(;;;;;;!**.jar;!module-info.class)] 
(Can't process class 
[com/sun/security/cert/internal/x509/X509V1CertImpl.class] (Unsupported 
version number [55.0] (maximum 54.0, Java 10)))

Due to this version incompatibility, most usage of proguard is not possible.

Upstream has fixed the issue in version 6.1.

Br,
Timo
