[jbosstools-issues] [JBoss JIRA] (JBDS-1895) Add/Remove operations on a VDB should block other operations on the VDB
Add/Remove operations on a VDB should block other operations on the VDB
-----------------------------------------------------------------------
Key: JBDS-1895
URL: https://issues.jboss.org/browse/JBDS-1895
Project: Developer Studio (JBoss Developer Studio)
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: teiid
Affects Versions: 4.1.0.GA
Reporter: Marc Shirley
Assignee: Barry LaFond
As adding/removing objects from a VDB results in filesystem operations of adding/removing
indexes, this should result in a blocking of additional operations against the VDB. If
latency with the filesystem is large enough (for example, on a network filesystem) and no
blocking is performed, multiple operations can be performed on the VDB resulting in the
below exception:
!MESSAGE Unhandled event loop exception
