Backport of Java 9 CompletableFuture, Flow and SubmissionPublisher API for Java 8

java9-concurrent-backport

java9-concurrent-backport is a backport of the upgraded (JEP 266) Java 9 CompletableFuture API (extended by the new Java 12 CSR JDK-8211010 exception handling methods) for Java 8. In addition, it contains a Java 8 version of the new Java 9 reactive-streams Flow and SubmissionPublisher API (also JEP 266) and of the new Java 9 Collections factory methods from JEP 269 (updated to the Java 14 implementation).

The API is exactly the same as in Java 14 with the exception that it doesn't live in the package java.util(.concurrent) but rather in the package java9.util(.concurrent).

The JEP 269 convenience factory methods for collections are located in companion classes for the corresponding java.util interfaces:

• java9.util.Lists
• java9.util.Maps
• java9.util.Sets

Maven:

<dependency>
    <groupId>net.sourceforge.streamsupport</groupId>
    <artifactId>java9-concurrent-backport</artifactId>
    <version>2.0.5</version>
</dependency>

The minimum runtime requirement is OpenJDK (Oracle) Java 8.

java9-concurrent-backport's Issues

JDK-8200520: ForkJoin tasks interrupted after shutdown

Apparently a bug in the ForkJoinPool shutdown detection:

https://bugs.openjdk.java.net/browse/JDK-8200520

Add OSGI headers

The current package lacks OSGI header information (such as Bundle-Export, Bundle-Version etc.) which render it not suitable for running in OSGI environments without some wrapping involved.

Missing AutoCloseable in SubmissionPublisher

hi @stefan-zobel ,

I found the SubmissionPublisher didn't implement the AutoCloseable interface,
when I tried to surround "try (SubmissionPublisher<...> pub = new SubmissionPublished<>())"
