From comment : #17259 (comment).
During the JDK 17 upgrade(#17168), 5 test methods across 4 files use string concatenation patterns that can be replaced with Java 15+ text blocks. Since text blocks require JDK 15+, these should be addressed after the JDK 17 migration.

Affected Files/Methods

1. TreeWalkerTest.java

   • testRequiredTokenIsEmptyIntArray()

2. TreeTableTest.java

   • testFindNodesIdent()
   • testFindNodesAllClassDefs()

3. GeneratedJavaTokenTypesTest.java

   • testTokenNumbering()

4. CommitValidationTest.java

   • testRevertCommitMessage()

Before:

String query = "/CLASS_DEF" + "\n" + "//IDENT";

After:

String query = """ /CLASS_DEF //IDENT""";
