Hi Max,

I changed the following in the new webrev :

http://cr.openjdk.java.net/~mbaesken/webrevs/8205525.7/

- What will the output look like? Is it "/tmp/x.jar:100"?

Yes it look like this :

line too long (/testdata/jars/file_with_long_line_1.jar:2)

Best regards, Matthias

SecurityProperties.java: - Please add the copyright+license header to the new file. - The "jdk.includeInExceptions" definition says there can be "Leading and trailing whitespaces". You might need to call trim() on each token. java.security: - I would suggest saying "classes from the java.util.jar package" or just "when parsing a jar file". Others: - What will the output look like? Is it "/tmp/x.jar:100"? If I read correctly, the line number is of the manifest and not the jar file.
