Changeset 339 for trunk/openjdk/hotspot

Timestamp:

Message:

Switch JNI calling convention from stdcall to _System on OS/2.

This makes JNI DLLs to be compatible with IBM Java (which uses
the _System cconv) and fixes applications using such DLLs (like
the standard LVMGUI and TCP/IP configuration OS/2 tools
written in Java).
