[GitHub] [netbeans] naotsugu opened a new issue, #4646: JavadocImports throws exception due to incorrect string trim

naotsugu opened a new issue, #4646:
URL: https://github.com/apache/netbeans/issues/4646

   ### Apache NetBeans version
   
   Apache NetBeans 15
   
   ### What happened
   
   An exception is raised if an attribute is specified in the JavaDoc to be trimmed.
   
   ```
   java.lang.StringIndexOutOfBoundsException: begin 0, end 7, length 6
   at java.base/java.lang.String.checkBoundsBeginEnd(String.java:4604)
   at java.base/java.lang.String.substring(String.java:2707)
   at org.netbeans.modules.java.editor.base.javadoc.JavadocImports.processDocTreeNode(JavadocImports.java:824)
   at org.netbeans.modules.java.editor.base.javadoc.JavadocImports.access$100(JavadocImports.java:81)
   at org.netbeans.modules.java.editor.base.javadoc.JavadocImports$1.scan(JavadocImports.java:135)
   at org.netbeans.modules.java.editor.base.javadoc.JavadocImports$1.scan(JavadocImports.java:117)
   at com.sun.source.util.DocTreeScanner.scanAndReduce(DocTreeScanner.java:88)
   at com.sun.source.util.DocTreeScanner.scan(DocTreeScanner.java:103)
   at com.sun.source.util.DocTreeScanner.visitReturn(DocTreeScanner.java:419)
   ```
   
   ### How to reproduce
   
   An exception will be thrown if a character containing spaces such as `{@ ` is present in the JavaDoc.
   
   ```
   /**
    * {@ 
    */
   ```
   Note that this character contains spaces.
   
   The following incorrect trim process is the cause.
   
   
   org.netbeans.modules.java.editor.base.javadoc.JavadocImports.java
   
   ```java
   int errorBodyLength = body.trim().substring(0, body.length()).trim().length();
   ```
   
   I do not understand the intent of the above, but I speculate that the following is appropriate.
   
   ```java
   int errorBodyLength = body.trim().length();
   ```
   
   Added in this pull. [https://github.com/apache/netbeans/pull/2954](https://github.com/apache/netbeans/pull/2954)
   
   
   
   ### Did this work correctly in an earlier version?
   
   Apache NetBeans 12.4
   
   ### Operating System
   
   MacOS 12.5.1
   
   ### JDK
   
   OpenJDK 64-Bit Server VM Corretto-18.0.0.37.1
   
   ### Apache NetBeans packaging
   
   Apache NetBeans binary zip

   thanks for looking into this. Just as note: no need to create an issue if you are working on a PR anyway. PRs are sufficient :)
