> Logging of XIDs/TransactionIds is wrong
> ---------------------------------------

> Key: GERONIMO-6542
> URL: https://issues.apache.org/jira/browse/GERONIMO-6542
> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: transaction manager
> Environment: JBoss Fuse 6.1-610379, Apache Geronimo
> TransactionManager 3.3.1
> Reporter: Jörn Gersdorf
> Priority: Minor
> Attachments: GERONIMO-6542__Fix_wrong_logging_of_transaction_ids.patch

>
> Transaction IDs are logged in a wrong format by XidImpl.toString().
> We are currently investigating issues in a distributed transaction setup
> involving WebsphereMQ and try to correlate hanging transactions from MQ with
> transaction behaviour by Aries/Geronimo. Therefore we set loglevel
> {{org.apache.geronimo.transaction.manager}} to {{TRACE}} which lets
> {{WrapperNamedXAResource}} nicely log all XA activities.
> However, transaction XIDs are logged in a wrong format. E. g. the transaction
> Xid
> {{363720AB4C0100006F72672E6170616368652E61726965732E7472616E73616374696F6E00000000000000000000000000000000000000000000000000000000}}
>
> will be logged as
> {{363720ffffffab4c1006f72672e6170616368652e61726965732e7472616e73616374696f6e0000000000000000000000000000}}.
> This makes it hard to find and correlate transaction Xids in the log.
> Reason lies in {{XidImpl.toString()}} and is twofold:
> 1. {{Integer.toHexString(bgid[i])}} will append a single byte as just one
> character for byte values {{0 <= bgid[i] <= 15}} (e. g. "1" instead of "01").
> 2. {{bgid[i]}} is a signed byte value. Negative values will be logged wrongly
> (e. g. "ab" will be logged as "ffffffab").
> Patch solving these issues is attached.
