Daniel Watford commented on OFBIZ-12118:
----------------------------------------
When running ofbiz from the command line using gradle, the URLs passed to
UtilXml.readXmlDocument are file URLs, e.g.
{{[file:/ofbiz/build/resources/main/component-load.xml|file://ofbiz/build/resources/main/component-load.xml]}}
If running ofbiz from the ofbiz.jar file then the URLs passed to
UtilXml.readXmlDocument refer to resources in jar files, e.g.
{{jar:[file:/ofbiz/build/distributions/foo/ofbiz/lib/ofbiz.jar!/component-load.xml|file://ofbiz/build/distributions/foo/ofbiz/lib/ofbiz.jar!/component-load.xml]}}
There are a few JDK bugs related to caching of stream for URL resources,
including:
- [Bug ID: JDK-6947916 JarURLConnection does not handle useCaches correctly
(java.com)|https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6947916]
- [Bug ID: JDK-8155607 Closing an URLClassLoader instance affect another
URLClassLoader instance when getResourceAsStream() is being used
(java.com)|https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8155607]
The first bug is related to using caches with JarUrlConnections and is thought
to be fixed. However the second bug about closing a URLClassLoader seems very
similar in that file input streams are being closed unexpectedly.
Checking URLClassLoader sources, it does indeed use URLConnection to access jar
files. I wonder if the issue we are experiencing is due to the URLClassLoader
also accessing, and subsequently closing, ofbiz.jar before our
UtilXml.readXmlDocument gets a chance to run.
Based on this, avoiding use of caches when dealing URLConnections, unless you
know that no other thread is accessing the same resources, seems reasonable and
[~ieugen]'s PR should be applied to ofbiz.
