1.12 +Once the HSDB debugger has been launched, the threads list is displayed
1.13 +if launched with debuggee options (pid or core) in command line. If
1.14 +HSDB was launched without debuggee, empty screen is shown.
1.15 +</p>
1.16 +<p>File menu sub-menu options to attach, detach debuggee and exit tool.</p>
1.17 +<p>Tools menu sub-menus include:</p>
1.18 + <ul>
1.19 + <li>browsing of the annotated stack memory ("Stack Memory" button). It
1.20 + is currently annotated with the following information:
1.21 + <ul>
1.22 + <li> method names of the Java frames and their extents (supporting
1.23 + inlined compiled methods)
1.24 + <li> locations and types of oops, found using the oop map information
1.25 + from compiled methods (interpreter oop maps coming soon)
1.26 + <li> if a Java frame was interrupted by a signal (e.g., because of a
1.27 + crash), annotates the frame with the signal name and number
1.28 + <li> interpreter codelet descriptions for interpreted frames
1.29 + </ul>
1.30 + <li> finding which thread or threads caused a crash (currently
1.31 + identified by the presence of a signal handler frame - solaris-only)
1.32 + <li> browsing of oops using the Oop Inspector.
1.33 + <li> browsing of the java.lang.Thread object's oop.
1.34 + <li> Object Histogram and inspection of objects and liveness analysis therein.
1.35 + <li> Class Browser - view Java classes, bytecode disassembly,
1.36 + or create .class files for selected classes
1.37 + <li> native disassembly (sparc, x86 only) and nmethod disassembly with annotations for safepoint details.
1.38 + <li> view -XX flags, System properties, VM version of debuggee
1.39 + </ul>
1.40 +<p>Windows sub-menu options include:</p>
1.41 + <ul>
1.42 + <li> Windows sub-menu: Console window to run "CLHSDB" commands in GUI
1.43 + <li> Windows sub-menu: Debugger console of underlying native debugger (MS Windbg or dbx (if used))
