The hs_err6.pl perl script parses an existing hs_err file and annotates it with additional information. In particular the script will decode the the rather cryptic "Error ID" string as well as making an attempt to decorate the module-relative offsets (e.g., [jvm.dll+0x1234]) found in native stack listings with more useful symbolic names.
The script is provided as-is and is entirely unsupported. It works only on J2SE 6 reference platforms. To get started run with the --help option. Ideally, future versions of the JVM will integrate this feature and there'll be no need for the script.
