<td valign="top">On operating systems other than Windows, you can now use the <tt>user2</tt> event for the <tt>-Xdump</tt> option. The <tt>user2</tt> event is commonly used for taking system dump files with exclusive access without overriding the <tt>user</tt> event, which is generally left for taking Java dump files for performance investigations. </td>

<td valign="top">Objects that are created from classes <tt>Thread</tt> and <tt>Class</tt> are allocated in the tenure region directly and therefore, do not get moved by the garbage collector often. It takes time for such pre-tenured objects to get hashed and extended with a slot. To pre-hash those objects from the start and hence, improve the performance, <tt>-XX:+EnsureHashed:java/lang/Class,java/lang/Thread</tt> is added to the list of default options in the <tt>options.default</tt> file.</td>
