----------------------------------
Summary: Possible bug in AstBuilder Antlr4
Key: GROOVY-8598
URL: https://issues.apache.org/jira/browse/GROOVY-8598
Project: Groovy
Issue Type: Bug
Components: parser-antlr4
Reporter: Daniel Sun
Assignee: Daniel Sun
Fix For: 2.6.0-alpha-4, 3.0.0-alpha-3
From dev mailing list(http://groovy.329449.n5.nabble.com/Possible-bug-in-AstBuilder-Antlr4-tt5750881.html):
Hi Daniel,
I think I have found a bug in the antlr4 AstBuilder class.
Add this line:
import groovy.transform.CompileStatic
before this one in a GString template: [https://github.com/melix/groovy-core/blob/d9656842908acb403599cf574f509aea2737be47/subprojects/groovy-groovydoc/src/main/resources/org/codehaus/groovy/tools/groovydoc/gstringTemplates/classLevel/classDocName.html#L27]
And run GroovyDocToolTest. Some tests will fail with:
java.lang.ClassCastException: org.codehaus.groovy.ast.ImportNode cannot be cast to org.codehaus.groovy.ast.stmt.Statement
