[jira] [Reopened] (DERBY-5615) NPE in Store when running SELECT in
a read-only database accessed via the classpath subprotocol when
authentication, authorization, and Java security are turned on
[ https://issues.apache.org/jira/browse/DERBY-5615?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Knut Anders Hatlen reopened DERBY-5615:
---------------------------------------
The fix for this issue seems to cause problems for the tests on Windows. DatabaseClassLoadingTest fails to delete dclt.jar when it's done. Reopening the issue.
I've found out how to fix it, but I don't understand why it's failing in the first place.
Originally, in CPFile, the getInputStream() method and the getURL() method were almost identical, only that the former used ClassLoader.getResourceAsStream() and ClassLoader.getSystemResourceAsStream() whereas the latter used ClassLoader.getResource() and ClassLoader.getSystemResource().
To minimize the duplication, the 1b patch rewrote getInputStream() so that it essentially just returned getURL().openStream(), plus some error checking.
If I reintroduce the code duplication, the test runs cleanly on Windows again. So there must be something different with that approach, I just haven't figured out what.

> I get an NPE trying to select from a table on which I don't have select privilege. The database is stored in a jar file accessed via the classpath protocol. BUILTIN authentication and sql authorization are turned on in the database. Running under a Java security manager. I will attach a repro. Here is the NPE:
