Network Server Gives NPE if SQLException has null arguments (e.g. for ERROR
XBM0H)
------------------------------------------------------------------------------------
Key: DERBY-128
URL: http://issues.apache.org/jira/browse/DERBY-128
Project: Derby
Type: Bug
Components: Network Server
Versions: 10.0.2.1
Environment: Linux
Reporter: Kathey Marsden
Priority: Minor
Network server
Network Server throws an NPE because one of the arguments of the SQLException
is null. It shouldn't do so.
To reproduce try to create a database in the root directory on Linux. Do not
run in security manager. The trace below came from an extra '/' in the url in
NSinSameJVM.java
The issues are:
1) Network Server throws an NPE because one of the arguments of the
SQLException is null in this code. It shouldn't do so.
// arguments are variable part of a message
Object[] args = ce.getArguments();
for (int i = 0; args != null && i < args.length; i++)
sqlerrmc += args[i].toString() + separator;
2) This exception seems to have null arguments which doesn't seem right.
ERROR XBM0H: Directory /NSinSameJVMTestDB cannot be created.
ERROR XBM0H: Directory /NSinSameJVMTestDB cannot be created.
