[jira] Commented: (HARMONY-5968) [pack200][classlib] NumberFormatException in NewAttributeBands.readNumber()

["Andrew Cornwall (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-5968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12628155#action_12628155 ] 

Andrew Cornwall commented on HARMONY-5968:
------------------------------------------

Even when unpacked using Sun's unpack and repacked with -E1, the error still exists (in the same place). 

Looks like the string it's parsing is:
TB(7)[RCH](8,9)[PH]()[]

> I have a test case which causes a NumberFormatException when doing NewAttributeBands.readNumber(). It appears that digits is "" (an empty String) so the return line:
> return Integer.parseInt((negative ? "-" : "") + new String(digits))
> is doing Integer.parseInt(""), which causes the exception.
> Unfortunately, the test case is proprietary code, so I've sent it to Sian via email.
