[weld-issues] [JBoss JIRA] Closed: (WELD-522) Weld makes my Java SE app startup time >100x slower

Weld makes my Java SE app startup time >100x slower ---------------------------------------------------- Key: WELD-522 URL: https://issues.jboss.org/browse/WELD-522 Project: Weld Issue Type: Bug Components: Performance and Scalability Affects Versions: 1.0.1.Final Environment: Java 6, Weld 1.01 SE + lots of jars on the classpath Reporter: Morten Christensen Assignee: Pete Muir Booting my Java SE app without weld takes << 1s BUT the 1 line for initializing weld to autowire my app takes at least 4-5 seconds. My app is not so big and consist of ~20-30 singletons that must be wired + various other non-weld stuff. I have lots of stuff on my classpath so I suspect that could be why weld is going crazy. I guess this could be improved if I can have weld limited to work only inside my own jar and/or only work with specific classes/packages. P.S. With breakpoints enabled in a debugger and a bit of unluck, I was even able to have welds initialization to take ~ 5 minutes one day (reduced to seconds again after I removed all breakpoints though).
