Key: JCR-2905
URL: https://issues.apache.org/jira/browse/JCR-2905
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.2.2
Reporter: Xiaoming Shi
DateFormat.getDateTimeInstance() is very expensive, we can cache it to improve
performance
In the file:
./jackrabbit-2.2.2/jackrabbit-core/src/main/java/org/apache/jackrabbit/core/observation/EventJournalImpl.java
line: 356
DateFormat.getDateTimeInstance() is called in a critical section. We can move
it outside the critical section to increase the concurrency. It's better for us
to add a class member field to store the value.
This is similar to the Apache bug:
