NOTE: If using Java 10+, leveraging the `release` flag might be an easier solution, see above.

To use Java 6 or Java 7, the following tasks need to be configured:

* `JavaCompile` task to fork and use the correct Java home
* `Javadoc` task to use the correct `javadoc` executable
* `Test` and the `JavaExec` task to use the correct `java` executable.

With the usage of Java toolchains, this can be done as follows:

==== Worker API: working directory of a worker can no longer be set

Since JDK 11 no longer supports changing the working directory of a running process, setting the working directory of a worker via its fork options is now prohibited.
All workers now use the same working directory to enable reuse.
Please pass files and directories as arguments instead. See examples in the <<worker_api.adoc#worker_api, Worker API documentation>>.

	// and nExits subprocesses that exit immediately.
	//
	// When issue #61080 was present, a long-lived "hang" subprocess would
	// occasionally inherit the fork/exec status pipe from an "exit" subprocess,
	// causing the parent process (which expects to see an EOF on that pipe almost
	// immediately) to unexpectedly block on reading from the pipe.
