<div dir="ltr"><div>Hello,</div><div><br></div><div>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. <br></div><div><br></div><div>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 </div><div>* highlight potential problems such as overloaded CPU, low physical memory, the presence of OOME in the recent exceptions, LD_LIBRARY_PATH being set, etc,</div><div>* generate an "executive summary" for a high-level overview, for example, by front-line support,<br></div><div>* 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),</div><div>* provide the ability to highlight all addresses "near" the selected address, including registers, threads, and memory-mapped regions.</div><div><br></div><div>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.</div><div><br></div><div>Kind regards,</div><div>Maxim.<br></div><div><br></div><div>References:</div><div>* <a href="https://docs.oracle.com/javase/10/troubleshoot/fatal-error-log.htm">https://docs.oracle.com/javase/10/troubleshoot/fatal-error-log.htm</a></div><div><br></div></div>
