Bug#925225: gradle: Fix gradle compatibility with OpenJDK 8

[Tiago Stürmer Daitx]

Package: gradle
Version: 4.4.1-5
Severity: normal

Dear Maintainer,

Since the fix for bug #909905 in gradle 4.4.1-1 it has been not possible
to run the generated binaries with OpenJDK 8.

The patch introduced in 4.4.1-1 was loosely based on the actual upstream
patch and - differently from upstream - it replaced OpenJDK 8 classloading
with OpenJDK 9+ classloading scheme. The upstream patch modified
classloading to _add_ OpenJDK 11 support. The 4.4.1-1 also modified
gradle's Depends: to java 9.

gradle 4.4.1 in itself is actually compatible with OpenJDK 8 and the
packaging just added the minimum support to build and run it with OpenJDK
11. Still, that shouldn't be done in a way to remove the possibility of
running gradle with OpenJDK 8.

Regards,
Tiago
