Hello OpenEJB Developers!
I am using OpenEJB embedded in a wicket web application running on Jetty.
Now I wanted to trace JPA / JTA operations in my test environment and turned the "transaction" logging level to "debug".
Here are the relevant snippets from my configuration:
====== Turned on external logging configuration in test case setup =========
....
System.setProperty("openejb.logger.external", "true");
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
....
====== Extract from my log4j.properties file ========
log4j.rootLogger = fatal,C
...
log4j.category.Transaction = debug
...
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.layout = org.apache.log4j.SimpleLayout
=======================================
This led to an endless loop in the method org.apache.openejb.util.Memoizer.compute(..)
on several debug messages emitted by the class org.apache.openejb.core.transaction.JtaTransactionPolicy.
Here is an example message copied from the source code:
JtaTransactionPolicy.beginTransaction(JtaTransactionPolicy.java:235)
txLogger.debug("TX {}: Started transaction {}", transactionType, transaction);
The message key (ok, this cannot be a key anyway) is not found in
\openejb-core-3.1.jar\org\apache\openejb\util\resources\Messages.properties
so "TX {}: Started transaction {}" is passed on to java.text.MessageFormat.
But MessageFormat.makeFormat(..) expects arguments numbers in the braces and throws an IllegalArgumentException.
I solved the problem for myself by replacing all occurences of "{}" in all debug messages in this file (see below) and
copied the resulting class to openejb-core-3.1.jar.
Maybe the reason for this bug is that I my JDK version is not compatible?
makeFormat(..) could have had a default behaviour replacing all {} with {<{} position>} in a JDK < 1.5....?
Anyway, replacing JtaTransactionPolicy with my variant would be helpful for my configuration.
