Paul Spencer created KARAF-7435: ----------------------------------- Summary: Setting a configuration parameter to null throws an NPE. Key: KARAF-7435 URL: https://issues.apache.org/jira/browse/KARAF-7435 Project: Karaf Issue Type: Bug Components: karaf Affects Versions: 4.3.6 Reporter: Paul Spencer
Setting a configuration parameter to null throws a NullPointerException. The specification, [https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.configurator.html], is silent on the use of null as a property value, but includes the following "If a requested conversion cannot be performed, then the configuration is not processed and the Configurator implementation should log an error."; in addition the configuration parameter are stored in a Dictionary structure which requires a non-null key and non-null value. Although the json format supports 'null' as value and OSGi confutation appears to required non-null values, should Karaf log something like "Null value for <Property Name> not supported." instead of throwing a NPE? *** * Thrown exception *** java.lang.NullPointerException: null at org.apache.karaf.config.core.impl.JsonConfigInstaller.setConfig(JsonConfigInstaller.java:87) ~[?:?] at org.apache.karaf.config.core.impl.JsonConfigInstaller.update(JsonConfigInstaller.java:66) ~[?:?] at org.apache.felix.fileinstall.internal.DirectoryWatcher.update(DirectoryWatcher.java:1117) [!/:3.7.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.update(DirectoryWatcher.java:919) [!/:3.7.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.doProcess(DirectoryWatcher.java:488) [!/:3.7.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.process(DirectoryWatcher.java:365) [!/:3.7.4] at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:316) [!/:3.7.4] *** * etc/foo.json *** { "myNullValue":null } -- This message was sent by Atlassian Jira (v8.20.7#820007)
