* ScriptTransformationService: Fix engine closed too early Currently, there are two issues: When a ScriptRecord is cleared from the cache, the ScriptTransformationService currently closes the ScriptEngine itself, without involving the ScriptEngineManager. If a transformation script is invoked again after it has been cleared from the scriptCache, the ScriptEngineManager::createScriptEngine call makes the ScriptEngineManager first remove the old engine from its internal "store", which includes invoking the scriptUnloaded hook. This invocation can cause an exception because the engine is already closed (by ScriptTransformationService) and hence function/method invocations inside the engine are not possible anymore. Ff the engine implement Compilable, it is even closed two times by ScriptTransformationService, possibly causing an exception if the ScriptEngine doesn't handle multiple close() calls gracefully. These issues are fixed by properly notifying the ScriptEngineManager when an engine should be removed and leaving the removal handling to the ScriptEngineManager. The issues were discovered while working on #5062. Signed-off-by: Florian Hotze <dev@florianhotze.com>
openHAB Core
This project contains core bundles of the openHAB runtime.
Building and running the project is fairly easy if you follow the steps detailed below.
Please note that openHAB Core is not a product itself, but a framework to build solutions on top. It is picked up by the main openHAB distribution.
This means that what you build is primarily an artifact repository of OSGi bundles that can be used within smart home products.
1. Prerequisites
The build infrastructure is based on Maven. If you know Maven already then there won't be any surprises for you. If you have not worked with Maven yet, just follow the instructions and everything will miraculously work ;-)
What you need before you start:
- Java SE Development Kit 21
- Maven 3 from https://maven.apache.org/download.html
Make sure that the mvn command is available on your path
2. Checkout
Checkout the source code from GitHub, e.g. by running:
git clone https://github.com/openhab/openhab-core.git
3. Building with Maven
To build this project from the sources, Maven takes care of everything:
- set
MAVEN_OPTSto-Xms512m -Xmx1024m - change into the openhab-core directory (
cd openhab-core) - run
mvn clean spotless:apply installto compile and package all sources
If there are tests that are failing occasionally on your local build, run mvn -DskipTests=true clean install instead to skip them.
For an even quicker build, run mvn clean install -T1C -DskipChecks -DskipTests -Dspotless.check.skip=true.
