SC: byte[] and Byte[] typecasting issue

    XMLWordPrintableJSON

Details

    • Bug
    • Status: Closed
    • Major
    • Resolution: Fixed
    • 2.0.1
    • 2.0.2
    • Static compilation
    • None

    Description

      import groovy.transform.*

@CompileStatic
class Bug3 {
    String test() {
        def b = "foo".bytes
        new String(b)
    }
}

new Bug3().test()

      Static compilation is not happy with the above, thinking b is a Byte[] instead of byte[], yielding the following error:

      org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '[B@727a9fa7' with class '[B' to class 'byte'
	at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.castToNumber(DefaultTypeTransformation.java:146)
	at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.byteUnbox(DefaultTypeTransformation.java:46)
	at Bug3.test(ConsoleScript34:7)

      Whereas, if you explicitly type the variable with byte[] it's okay.
