I would suggest to create a separate issue to follow up the spec clarification and keep this PR to fix the implementation. The version parsing code is tricky.

The spec may needs some clarification. Yes, I think we should fix the consistency issues although the cases where the inconsistency show up seem unusual.

I reviewed the change. It is reasonable to fix the parsing of the pre-release version and the build version be consistent with parsing of the version number which currently skips consecutive delimiters. The spec is unclear on whether an empty token separated by the delimiters is ignored. The spec may needs some clarification. - PR: https://git.openjdk.java.net/jdk/pull/5679

RFR: 8250678: ModuleDescriptor.Version parsing treats empty segments inconsistently
Could you please review the 8250678 bug fixes? The `parse` method of ModuleDescriptor.Version class behaves incorrectly when the input string contains consecutive delimiters. The `parse` method treats strings as three sections, but the parsing method differs between the method for the version sections and the ones for others. In version sections, the `parse` method takes a single character in a loop and determines whether it is a delimiter. In pre and build sections, the parse method takes two characters in a loop and determines whether the second character is the delimiter. Therefore, if the string contains a sequence of delimiters in pre or build section, the `parse` method treats character at the odd-numbered position as a token and the one at even-numbered as a delimiter. A string containing consecutive delimiters is an incorrect version string, but this behavior does not follow the API specification. https://download.java.net/java/early_access/jdk18/docs/api/java.base/java/lang/module/ModuleDescriptor.Version.html Therefore, I propose to fix the parsing method of pre and build section in the same way as the version. - Commit messages: - 8250678: ModuleDescriptor.Version parsing treats empty segments inconsistently Changes: https://git.openjdk.java.net/jdk/pull/5679/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk=5679=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8250678 Stats: 26 lines in 2 files changed: 11 ins; 14 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/5679.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5679/head:pull/5679 PR: https://git.openjdk.java.net/jdk/pull/5679
