----------------------------------
Summary: ConcurrentModificationException on rebind to persisted
state (in BrooklynProperties)
Key: BROOKLYN-404
URL: https://issues.apache.org/jira/browse/BROOKLYN-404
Project: Brooklyn
Issue Type: Bug
Reporter: Aled Sage
With Brooklyn 0.10.0-SNAPSHOT, when attempting to restart Brooklyn (binding to
existing persisted state), it hit a {{ConcurrentModificationException}}.
This failure only happens occasionally.
Starting Brooklyn such that it fails fast if there are any persistence errors:
{noformat}
./bin/brooklyn launch --persist auto --persistenceDir
`pwd`/$PERSISTENCE_DIR/data --highAvailability disabled
--startupFailOnPersistenceErrors --startupFailOnManagedAppsErrors
{noformat}
The info log showed:
