Source: openjdk-11
Version: 11.0.4+11-1
Severity: normal

OpenJDK generates five private classes CharacterData{00,01,02,0E,Latin1}
in the java.lang package which contain a timestamp and capture the build
path in the comments. This affects the reproducibility of the src.zip
file installed by the openjdk-11-source package.

I'm attaching a patch addressing this issue.

Description: Makes the generated character data classes reproducible (removes a timestamp and trims a build path captured in the comments)
