Has anyone got a list of recommended non-leaking third party frameworks ? We are using:
- Tapestry 4.1 - Cayenne 1.2.1 - Postgres Driver 8.2.5.0.4 - JDBC3 8.2-504 - JDBC API 2.0 - OGNL 2.6.7 - Log4j 1.2.13 - Hivemind DWR 1.1.beta3 - Commons Loggings 1.0.3 -------- Original-Nachricht -------- Datum: Fri, 10 Aug 2007 04:58:18 +0200 Von: "Hans Jörg Hessmann" <[EMAIL PROTECTED]> An: Tapestry users <users@tapestry.apache.org> Betreff: Re: Memory leaks in Tapestry 4.1 > There is an excellent tool for post-mortem memory analyzation: > https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0eaafd5-6ffd-2910-019c-9007a92b392f. > Just add -XX:+HeapDumpOnOutOfMemoryError to the startup parameters of > your JVM.
