--- Comment #5 from Sebastien Tardif <sebtar...@ncf.ca> --- The implementation of GlassFish "working" on JDK 6, is avoiding "systematic" synchronization on the instance, and so that seems to have been enough to be fast, see http://grepcode.com/file/repo1.maven.org/maven2/org.glassfish.web/war-util/3.0/org/glassfish/web/loader/WebappClassLoader.java In other words, they have at least tried to synchronized the smaller block as possible in all cases, and also with dubious construct, used some optimization similar to read/write lock. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
