VDB deployment fails if metadata index file has been removed due to NPE during
Index.initialize
-----------------------------------------------------------------------------------------------
Key: TEIID-1739
URL: https://issues.jboss.org/browse/TEIID-1739
Project: Teiid
Issue Type: Bug
Components: Server
Affects Versions: 7.5
Reporter: Larry O'Leary
Assignee: Steven Hawkins
VDB couldn't be deployed, so customer restarted SOA-P server and the server.log
shows:
DEPLOYMENTS MISSING DEPENDENCIES:
Deployment "VDBDeployer" is missing the following dependencies:
Dependency "SystemVDBDeployer" (should be in state "Create", but
is actually in state "**ERROR**")
DEPLOYMENTS IN ERROR:
Deployment "SystemVDBDeployer" is in error due to the following reason(s):
java.lang.NullPointerException, **ERROR**
ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error
installing to Start: name=SystemVDBDeployer state=Create
java.lang.NullPointerException
at org.teiid.internal.core.index.BlocksIndexInput.close(BlocksIndexInput.java:65)
at org.teiid.internal.core.index.Index.initialize(Index.java:222)

Although we do not yet know what has caused this situation, the NPE is a direct result of
a bug in the way the index initialization is performed. In the event the file can not be
read, we should simply remove the index entry but we don't get this far because when
the file fails to be opened, we attempt to close it to ensure we cleanup our code. The
problem is, the object was never initialized due to the file not being opened and
therefore, we cause a NullPointerException:
Specifically, org.teiid.internal.core.index.BlocksIndexInput.close():
if (raf != null)
raf.close();
vraf.close();
should be something like:
if (raf != null)
raf.close();
if (vraf != null)
vraf.close();
