Configurable warnings in the tool window draw attention to unusual features of the crash:
A human-readable analysis of the crash:
Hold the mouse pointer over an address to try to resolve it.
Works for thread, stack, Java heap, dynamic libraries, and other addresses:
Pick the Find Address option from the context menu
to highlight the address under the cursor and addresses near it everywhere in the log file:
Addresses do not have to match textually or even appear in the log. For example, address pointing into a memory-mapped region will highlight that region in the log.
Numbers that denote the size are converted into a more human-readable form:
Signals, registers, and common thread names, some JVM terms also have documentation hints.
Go to declaration for Java symbols and classes;
requires Java support in the IDE and the corresponding project with the classes opened:
