[hibernate-issues] [JIRA] (HV-1955) NotBlankValidator is not consistent with Jakarta @NotBlank specs

Laurent Martelli ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate Validator ( https://hibernate.atlassian.net/browse/HV?atlOrigin=eyJpIjoiZmYyZWJmNmVhN... ) / Bug ( https://hibernate.atlassian.net/browse/HV-1955?atlOrigin=eyJpIjoiZmYyZWJm... ) HV-1955 ( https://hibernate.atlassian.net/browse/HV-1955?atlOrigin=eyJpIjoiZmYyZWJm... ) NotBlankValidator is not consistent with Jakarta @NotBlank specs ( https://hibernate.atlassian.net/browse/HV-1955?atlOrigin=eyJpIjoiZmYyZWJm... ) Issue Type: Bug Affects Versions: 8.0.0.Final Assignee: Unassigned Components: validators Created: 16/Jun/2023 03:30 AM Priority: Major Reporter: Laurent Martelli ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) The documentation for @NotBlank says “The annotated element must not be null and must contain at least one non-whitespace character. Accepts CharSequence.” and refers to Character.isWhitespace(char). But NotBlankValidator uses trim() whose definition of a “space character” is different from Character.isWhitespace(char). String.isBlank() (introduced in Java 11) would be a better implementation choice. If pre-Java 11 compatibility is required, Character.isWhitespace(char) could be be used.
