Summary :
This SAP Note addresses multiple issues related to the SAP Java Connector (JCo) including memory leaks in Java heap, CPIC and RFC errors, and incorrect API behaviors. Notable issues include a JCoException due to wrong APPC header versions, loss of RFC table data, infinite RFC logon attempts, and missing JCo trace information in server scenarios. Resolutions include software updates, handling improvements for RFC callbacks, and logon enhancements with external user data. It advises updating to SAP JCo 3.0.9 to rectify these errors and benefit from newly introduced features and enriched Java system property management functionalities. Users are directed to the SAP Service Marketplace for the necessary downloads and instructions.
