Hello,
I have run into a problem when running a JDBC4 JUnit test. The test is
compiled with Mustang (Java 1.6), and all you need in the test for the
problem to arise is a
'Class.forName("org.apache.derby.jdbc.EmbeddedDriver")'.
When the above codeline is executed, a
java.lang.ExceptionInInitializerError is raised with the following cause:
Caused by: java.security.AccessControlException: access denied
(java.util.PropertyPermission derby.debug.false read)
at
java.security.AccessControlContext.checkPermission(AccessControlContext.java:321)

The code causing the error is only reachable in sane builds, and is
located in 'impl.services.monitor.BaseMonitor.runWithState()':
if (SanityManager.DEBUG) {
// Look for the derby.debug.* properties.
if (applicationProperties != null) {
// MODIFIED [snip]
}
// MODIFIED - The error happens here!
addDebugFlags(System.getProperty(Monitor.DEBUG_FALSE), false);
addDebugFlags(System.getProperty(Monitor.DEBUG_TRUE), true); }
There are at least two workarounds; grant more permissions in the
derby_test.policy file (without a codebase argument), or use a
doPrivileged-block around the Class.forName() call.
However, the two options above do not seem right to me.
Can we move the doPrivileged-block down into the BaseMonitor class?
There is also a Properties variable in BaseMonitor named
systemProperties, but glancing at the code tells me it might be null
(haven't checked the consequences of that).
Can anyone advice on this?
