[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-9287) NullPointerException in org.jboss.tools.cdi.seam.config.core.xml.SAXParser
[
https://issues.jboss.org/browse/JBIDE-9287?page=com.atlassian.jira.plugin...
]
Viacheslav Kabanovich commented on JBIDE-9287:
----------------------------------------------
We use XMLReaderFactory.createXMLReader() to create XMLReader instance and expect that it
will find it in classpath. However, Eclipse has many class loaders and
org.xml.sax.helpers.NewInstance class be loaded by a class loader that does not have a
parser implementation. We have not provided explicit dependency on a plugin that has it.
If our SAXParser is invoked through plugin which has no parser implementation in all
dependency its tree, then XMLReaderFactory.createXMLReader() will fail. It seems that the
probability of it is very low, so that we have to decide if we should create that explicit
dependency (by the way, our test plugins have it); or just log message if failure
happens.
