Hi Chamila, With the latest code as of today (see last commit) and run into the exceptions (see below) when bringing up the cartridge agent ? Not sure if something is missing or the code is simple not yet ready ?
I attached the logs as well,
Thanks
Martin

Hi Chamila,
I was just wondering if you already merged these fixes back to the master (or
by when ) ?
I think I am hitting these issues, see exceptions below,
Thanks

Hi,
I'm in the process of getting the JCA to a matching state with the PCA. As a
part of this I copied over the integration test that was written by Imesh for
the PCA, to simplify error checks and find bugs in the JCA.
There was an issue in the CartridgeEventListener where
TopologyManager.acquireReadLock() was called after a conditional return
statement. The lock is released in the finally{} block and thus it executes
before the return statement completes, i.e. before actually acquiring the lock.
Another issue I've found so far is the -Dthrift.client.config.file.path system
property and the thrift-client-config.xml being missing in the Cartridge agent
product assembly.
I will soon submit a PR with a stable JCA.
Any feedback, ideas are appreciated! :)
