### New and noteworthy
|
|
|
|
#### New Rules
|
|
|
|
* The new Java rule {% rule "java/bestpractices/AvoidReassigningCatchVariables" %} (`java-bestpractices`) finds
|
|
cases where the variable of the caught exception is reassigned. This practice is surprising and prevents
|
|
further evolution of the code like multi-catch.
|
|
|
|
### Fixed Issues

|
|

|
|
* [#2431](https://github.com/pmd/pmd/issues/2431): \[java] InvalidLogMessageFormatRule throws IndexOutOfBoundsException when only logging exception message
|
|
* [#2439](https://github.com/pmd/pmd/issues/2439): \[java] AvoidCatchingThrowable can not detect the case: catch (java.lang.Throwable t)
|
|
* java-performance
|
|
* [#2441](https://github.com/pmd/pmd/issues/2441): \[java] RedundantFieldInitializer can not detect a special case for char initialize: `char foo = '\0';`
|
|
|
|
### API Changes
|
|
|
|
* XML rule definition in rulesets: In PMD 7, the `language` attribute will be required on all `rule`
|
|
elements that declare a new rule. Some base rule classes set the language implicitly in their
|
|
constructor, and so this is not required in all cases for the rule to work. But this
|
|
behavior will be discontinued in PMD 7, so missing `language` attributes are now
|
|
reported as a forward compatibility warning.
|
|
|
|
#### Deprecated API
|
|
|
|
##### For removal
|
|
|
|
* {% jdoc !!pmd-java::lang.java.ast.ASTThrowStatement#getFirstClassOrInterfaceTypeImage() %}
|
|
