Use primitive wrapper valueOf method

Recipe IDorg.openrewrite.staticanalysis.PrimitiveWrapperClassConstructorToValueOf
Artifactorg.openrewrite.recipe:rewrite-static-analysis

The constructor of all primitive types has been deprecated in favor of using the static factory method valueOf available for each of the primitive type wrappers. Using valueOf enables object caching for frequently used values, reducing unnecessary heap allocations. Note that this changes identity semantics: valueOf may return cached instances (such as Boolean.TRUE or Integer values in [-128, 127]), so code that compares boxed values with ==/!=, relies on System.identityHashCode, or synchronizes on the boxed value may behave differently after this change.
