Hi, 1.0.0 contains several bug fixes, for example: BUG 304291: BlockLogBuffer computes non-portable checksums BUG 300956: LogOverflowException causes application to hang BUG 304299: JUnit test cases hang randomly and several new features, like added Maven 2 pom build file, synchronized log files access and so on.
See http://howl.objectweb.org/cvs/HOWL_1_0_0.html for more details. Also a new HOWL 1.0.1 release containing more bug fixes is available now. So, we may consider to use this version in Geronimo.

Now version of HOWL in Geronimo is 0.1.11. What do you think about its replacing with new one 1.0.0? Some problems are fixed in new HOWL version. One of them is of importance for correct Geronimo startup: class org.objectweb.howl.log.BlockLogBuffer from howl-logger-0.1.11.jar throws org.objectweb.howl.log.InvalidLogBufferException over check-up of log files availability using HOWL classes when we start Geronimo by command: java -jar bin/server.jar. Because it checks files' validity if they exist. One of verified parameters is the file content control sum. One value of this parameter is read from file header and another is calculated by function java.nio.ByteBuffer.hashCode(). If Geronimo is launched on one JDK at first and then - on another, class BlockLogBuffer can throw exception because algorithms of function hashCode() can be different and values of the checksum don't equal accordingly. This is bug in HOWL classes http://forge.objectweb.org/tracker/?group_id=92&atid=100092&func=detail&aid=304291 In new HOWL version 1.0.0 it is fixed by introduction of new boolean parameter. When the parameter equals 'false', control sum is calculated using hashCode() function. Otherwise the calculation is performed using ADLER-32 algorithm. If the jar with new HOWL version is added to maven repository and Geronimo sources are patched by using new parameter the exception won't appear. This is not a critical bug; however, I think it is better to use HOWL 1.0.0 for correct Geronimo launching on various JDK. Any ideas? Thanks, Nellya Udovichenko, Intel Middleware Products Division
