Why would Arjuna fail to start with ARJUNA012391 (with unlogged ARJUNA012225)?

[David Johnson]

50,000 foot overview

I am refactoring a large legacy application to java 17, addressing several generations of technical debt. Part of the refactoring includes swapping out hte defunct bitronix transaction manager for the Narayana + Arjuna combination.

At application launch, Arjuna is failing to start with the exception ARJUNA012391: Could not initialize object store 'null' of type 'com.arjuna.ats.internal.arjuna.objectstore.ShadowNoFileLockStore' .

The application runs on java 17 in a tomcat 10 container. The dev environment is Windows.

Work so far:

I have traced into the ObjectStoreAPI initStore(String name) to see there is an InvocationTargetException

I have confirmed that:

• the Arjuna environment variables are set to -Duser.dir=C:/arjuna/user -Duser.home=C:/arjuna/user
• the empty object store directories have been created by arjuna, and
• the directory permissions allow the application full control
• the classLoader's reflective calls to the constructor are not prohibited by the visibility
• the unlogged initial exception is com.arjuna.ats.arjuna.exceptions.ObjectStoreException: ARJUNA012225: FileSystemStore::setupStore - cannot access root of object store: PutObjectStoreDirHere\ShadowNoFileLockStore\defaultStore\
• The directory C:\arjuna\user\PutObjectStoreDirHere\ShadowNoFileLockStore\defaultStore exists and the jvm has full control of it (the jvm created it when arjuna tried to  initialize the first time)

[Michael Musgrove]

It's a strange one. Could you try explicitly setting the property to an absolute path so as to bypass the "user.dir" system property, something like "-DObjectStoreEnvironmentBean.objectStoreDir=/tmp/xyz"

If that also fails would it be possible for you to create a simple reproducer that we can try at our end?

[David Johnson]

Thank you Michael,

After single stepping into the constructor, this is exactly what I did. It is functional now.

It is reassuring to know that this is the correct response.
