Failure when parsing Javadoc containing {@link and no closing brace

[greg-at-moderne]

What version of OpenRewrite are you using?

Current main = 7de8e67

What is the smallest, simplest way to reproduce the problem?

    @Test
    void unclosedBraceOnLink() {
        rewriteRun(
          java(
            """
              class Test {
                 /**   
                  * {@link int
                  * Some other text.
                  * See {@link java.lang.String}
                  * @param arg description
                  */                  
                  void method(String arg) {
                  }
              }
              """
          )
        );
    }

in JavadocTest

What did you see instead / What is the full stack trace of any errors you encountered?

Caused by: org.openrewrite.java.JavaParsingException: Failed to convert for the following cursor stack:--- BEGIN PATH ---
JCCompilationUnit(sourceFile = Test.java)
JCClassDecl(name = Test, line = 1)

Context

• the problem goes away if I close the {@link with } on the same line. But this mistake is kind of popular when I looked through the open-source Java code, so I think we should do a better job handling this admittedly invalid input.
• Print equality issue with <!-- --> in JavaDoc #4248 is related
• so is Edge cases for Javadoc parsing #3650
