[jira] [Resolved] (GROOVY-6631) Static compilation fails around byte arrays

["Daniel Sun (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-6631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Sun resolved GROOVY-6631.
--------------------------------
    Resolution: Not A Problem
      Assignee: Daniel Sun

`i / 2` will yield a `BigDecimal`, e.g. 1 / 2 yields 0.5, not 0.

`data[i / 2]` should be modified as `data[(int) (i / 2)]`, the complete code is:
{code:java}
@groovy.transform.CompileStatic
class Test {
    byte[] parseStructuredString(String s) {
        byte[] data = new byte[s.length() / 2];
        for (int i = 0; i < s.length(); i += 2) {
            data[(int) (i / 2)] = (byte) ((Character.digit(s.charAt(i), 16) << 4) + Character.digit(s.charAt(i+1), 16));
        }
        return data
    }
}
{code}
