# Improvements to Java analysis
## General improvements
## New queries
| **Query** | **Tags** | **Purpose** |
|-----------------------------|-----------|--------------------------------------------------------------------|
| Double-checked locking is not thread-safe (`java/unsafe-double-checked-locking`) | reliability, correctness, concurrency, external/cwe/cwe-609 | Identifies wrong implementations of double-checked locking that does not use the `volatile` keyword. |
| Race condition in double-checked locking object initialization (`java/unsafe-double-checked-locking-init-order`) | reliability, correctness, concurrency, external/cwe/cwe-609 | Identifies wrong implementations of double-checked locking that performs additional initialization after exposing the constructed object. |
## Changes to existing queries
