Subject [jira] [Created] (JCR-3086) potential infinite loop around InternalVersionImpl.getSuccessors
Date Thu, 29 Sep 2011 12:04:45 GMT
potential infinite loop around InternalVersionImpl.getSuccessors
----------------------------------------------------------------

                 Key: JCR-3086
                 URL: https://issues.apache.org/jira/browse/JCR-3086
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 2.2.8, 2.4
            Reporter: Julian Reschke
            Assignee: Julian Reschke


There's an infinite loop waiting for happen when the underlying persisted version storage
is defect:


at
org.apache.jackrabbit.core.version.InternalVersionImpl.getSuccessors(InternalVersionImpl.java:148)

at
org.apache.jackrabbit.core.version.InternalVersionHistoryImpl.init(InternalVersionHistoryImpl.java:165)

at
org.apache.jackrabbit.core.version.InternalVersionHistoryImpl.reload(InternalVersionHistoryImpl.java:180)

at
org.apache.jackrabbit.core.version.InternalVersionHistoryImpl.getVersion(InternalVersionHistoryImpl.java:299)


(line numbers from 2.2)

What happens here is that when a version can not be instantiated, reload() is called, which
in turn calls init(), which, as part of piece of code labeled "fix legacy" will call getSuccessors(),
which in turn wants to instantiate versions.
