Creating a schema with DumpParseTree, DumpBindTree properties set causes
NullPointException.
--------------------------------------------------------------------------------------------
Key: DERBY-1119
URL: http://issues.apache.org/jira/browse/DERBY-1119
Project: Derby
Type: Bug
Versions: 10.2.0.0, 10.1.2.0
Reporter: Satheesh Bandaram
Priority: Minor
Noticed it in 10.2, but also reproduces with 10.1.
Set the following property and then try creating a schema as follows:
derby.debug.true=DumpBindTree,DumpParseTree,DumpOptimizedTree
C:\p4clients\sat_52\bug>java -Dij.protocol=jdbc:derby: org.apache.derby.tools.ij
ij version 10.2
ij> connect 'tdb;user=sam';
ij> create schema mysam1;
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
I suspect the problem is because DDLStatementNode.java expects an object name
that most DDL statements set, but not CreateSchemaNode.java.
public String toString()
{
if (SanityManager.DEBUG)
{
return objectName.toString() + super.toString();
<==============
}
else
{
return "";
}
}
CreateSchemaNode.java:
/*
** DDLStatementNode expects tables, null out
** objectName explicitly to clarify that we
** can't hang with schema.object specifiers.
*/
initAndCheck(null);
