Rupert Westenthaler created STANBOL-903:
-------------------------------------------
Summary: NLPEngineHelper does not obtain wirte lock when creating
an AnalyzedText ContentPart in the initAnalyzedText utility method
Key: STANBOL-903
URL: https://issues.apache.org/jira/browse/STANBOL-903
Project: Stanbol
Issue Type: Bug
Components: Enhancer
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Priority: Minor
As the title says the #initAnalyzedText(ContentItem ci) method in the
NlpEngineHelper utility (o.a.s.enhancer.nlp module) does not use a write lock
when creating the content part.
Using a read lock for checking if the AnalysedText content part exists is fine,
but it is not yet created a write lock needs to be obtained to avoid creating
multiple AnalysedText content parts.
Users affected by this will notice IllegalStateExceptions with the message that
the AnalyzedText content part is already present. Also check that the
"NlpEngineHelper#initAnalysedText(...)" is mentioned in the Stacktrace as this
Exception may also originate from direct calls to
AnalysedTextFactory#createAnalysedText(..)"
