Yuriy Flyud created SCXML-248:
---------------------------------
Summary: Java 7 support for commons-scxml2
Key: SCXML-248
URL: https://issues.apache.org/jira/browse/SCXML-248
Project: Commons SCXML
Issue Type: Wish
Affects Versions: 2.0
Reporter: Yuriy Flyud
commons-scxml2 project is compiled with Java 8. Attempts to compile sources
with Java 7 fail because of usage of lambda expressions, etc. The problem
number two is usage of JDK 8+ Nashorn Script Engine in JSEvaluator that is not
available in JDK 7 (the one with Rhino). Tests for JSEvaluator fail on Java 7.
The good news is that all the Java 8 specific features are used only in the
env.groovy package, and Script Engine Replacement issue affects only
env.javascript package. All the core functionality can work, and actually
works, with Java 7.
I propose to extract the core functionlaity from the commons-scxml2 to
something like commons-scxml2-core, and make it Java 7 compatible.
There are currently no any known stable SCXML Engine implementations that
support latest SCXML specification, so disabling the Java 7 compliance forbids
many developers like me to use it in their products.
>From my side I can propose creating a fork on Git repository for Java 7
>compatible commons-scxml2 project in case you decide to leave everything as it
>is.
