Hello,

I am writing to inquire about the potential interest of the people 
involved in inspecting HotSpot crashes in a tool aimed at facilitating 
that inspection.

We at JetBrains have developed an internal plugin that helps both with 
filtering through dozens of reports quickly in order to find a pattern 
and for diving deep into a particular crash. In addition to the 
"standard" features such as syntax highlighting, folding, and structural 
navigation, it will
* highlight potential problems such as overloaded CPU, low physical 
memory, the presence of OOME in the recent exceptions, LD_LIBRARY_PATH 
being set, etc,
* generate an "executive summary" for a high-level overview, for 
example, by front-line support,
* pop up a tooltip for any recognized address describing its origin (for 
example, if it belongs to some thread's stack, the Java heap, a 
register, or a memory-mapped region),
* provide the ability to highlight all addresses "near" the selected 
address, including registers, threads, and memory-mapped regions.

If there is sufficient interest in creating a public and/or open-source 
variant of this internal plugin, I will pitch the idea to my employer. 
It shouldn't be too much work to create a public version.

Kind regards,
Maxim.
