Code coverage on JDK7 with Emma

The latest upgrade to JDK7 did go without any issues what so ever in terms of application functionality.

The only issue so far is with Emma which stopped recording code coverage and turned to breaking tests instead giving an "Illegal local variable table length 5 in method" error instead.

What you need is this:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.12</version>
  <configuration>
    <argLine>-XX:-UseSplitVerifier</argLine>
  </configuration>
</plugin>

Relative file paths on JBoss EAP 5.1.2

Apparently there was a change in which kind of file URLs are correct in JBoss EAP 5.1.2. This tiny little change caused a great deal of pain in my case throwing

"IllegalArgumentException: URI is not hierarchical" in one environment but not the other.

Very well. We use the PropertyPlaceholderConfigurer with relative paths for file locations to greatly simplify the configuration differences between deployement and development environments. This is all done by simply stating

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <value>config/application.properties</value>
    </property>
</bean> 

In the applicationContext.xml to load properties from a path relative to the execution path. Running the application with maven jetty makes development rapid and simply and almost no setup is required for new developers.

With the latest change in JBoss, this could have become a very big issue. However, after a long days fiddling, here's the solution with maintained behavior.

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <value>file:${user.dir}/config/application.properties</value>
    </property>
</bean>
