Hi,
To support the idea mentioned in the letter http://mail-archives.apache.org/mod_mbox/incubator-harmony-dev/200602.mbox/[EMAIL PROTECTED], I've tried to implement the file I/O part of the Harmony portlib using APR. The JIRA issue with the patch is http://issues.apache.org/jira/browse/HARMONY-751. The main difficulty to implement I/O function using APR was the lack of modularity in the classlib native code (the other (not portlib) modules relies on the portlib functions returning OS I/O handles (but APR uses its own handles)). Please, review the patch and comment if the efforts to move OS/platform specific code to APR make sense and can be useful. Marina
