Aled Sage created BROOKLYN-240:
----------------------------------
Summary: NPE starting Brooklyn when could not create persistence
directory
Key: BROOKLYN-240
URL: https://issues.apache.org/jira/browse/BROOKLYN-240
Project: Brooklyn
Issue Type: Bug
Reporter: Aled Sage
Priority: Minor
I launched Brooklyn, but it failed to create the persistence directory (as seen
with the error below).

The default is for it to continue with the startup. It then failed with the
exception shown below:

This was with Brooklyn a version of Brooklyn from incubator-brooklyn, and a
startup command like:
{noformat}
nohup bin/brooklyn launch --localBrooklynProperties
/home/users/myname/brooklyn-managed-processes/apps/xDuDKT2a/entities/BrooklynNode_zXt7gzFt/brooklyn-local.properties
--port 8443 --bindAddress 0.0.0.0 --persist auto >>
/home/users/myname/brooklyn-managed-processes/apps/xDuDKT2a/entities/BrooklynNode_zXt7gzFt/console
2>&1 </dev/null &
{noformat}
---
If the CLI {{startupFailOnPersistenceErrors}} is false (which is the default)
then I'd expect Brooklyn to startup without throwing an NPE.
