Improvements to Java analysis

Changes to existing queries

Query	Expected impact	Change
Equals method does not inspect argument type (java/unchecked-cast-in-equals)	Fewer false positive and more true positive results	Precision has been improved by doing a bit of inter-procedural analysis and relying less on ad-hoc method names.

Changes to QL libraries

• The virtual dispatch library has been updated to give more precise dispatch targets for Object.toString() calls. This affects all security queries and removes false positives that arose from paths through impossible toString() calls.
