             Summary: JDK ORB char conversion preceeded by empty string conversion fails with ArrayIndexOutOfBoundsException
                 Key: WFLY-7050
                 URL: https://issues.jboss.org/browse/WFLY-7050
             Project: WildFly
          Issue Type: Bug
          Components: IIOP
    Affects Versions: 10.1.0.Final
            Reporter: Konstantin Glazkov
            Assignee: Tomasz Adamski
         Attachments: empty_string_followed_by_char_conversion_suggested_fix.patch, empty_string_followed_by_char_conversion_unit_test_fix.patch

If IDL structure contains string and char fields, and generated *Helper#write method looks like
ostream.write_string (value.string_field); //empty string
ostream.write_char (value.char_field); //any char
without non-empty strings before char field, then write_char method will fail with stacktrace:
Caused by: java.lang.ArrayIndexOutOfBoundsException: 0
