ScripteEngineManagerFactory is not thread safe
----------------------------------------------
Key: SLING-1545
URL: https://issues.apache.org/jira/browse/SLING-1545
Project: Sling
Issue Type: Improvement
Components: Scripting
Affects Versions: Scripting Core 2.0.12
Reporter: Felix Meschberger
Fix For: Scripting Core 2.0.12
The ScriptEngineManagerFactory class is not thread-safe:
* Access to the engineSpiBundles, engineSpiServices fields (lists) are not
guarded
* Calls to refreshScriptEngineManager are not guarded
This may cause improper states under certain circumstances.
Accesses to these internal fields and methods should properly be guarded.
In addition, replacement of the List as collection of the SPI bundles and
service by Set should be considered.
