Embedding a Java runtime in the distribution would provide some benefits, such as allowing the Launcher, Daemon and Workers to run on it, removing the prerequisite of an installed Java runtime.
However, this does not fully remove the prerequisite, as the Wrapper itself would still need an installed Java runtime to execute.

Gradle needs a solution that covers the use-case of starting the Wrapper itself as well given its importance.

That will merge the `.md` files in `next` into a single file.
Atomically (as close to it as possible) add that file to `_content/doc` directory
of the website repository and remove the `doc/next` directory in this repository.

To begin the next release development cycle, populate the contents of `next`
with those of `initial`. From the repo root:

    > cd doc
    > cp -R initial/ next

        if (var.equalsType(t)) {
          // cycle detected, remove the entire cycle from the mapping so that
          // each type variable resolves deterministically to itself.
          // Otherwise, an F -> T cycle will end up resolving both F and T
          // nondeterministically to either F or T.
          for (Type x = arg; x != null; x = mappings.remove(TypeVariableKey.forLookup(x))) {}
          return;
        }
      }

```java
    val urlIterator = cache.urls()
    while (urlIterator.hasNext()) {

        urlIterator.remove()
      }
    }
```

### Troubleshooting

1. Valid cacheable responses are not being cached
