In other words: > boolean ret = NumberUtils.isNumber("0.4790"); > On 3.1, ret was true. In 3.3.1, ret is false. > Guessing that LANG-972 is related... comment in the code states: > // leading 0, but not hex, must be octal > This is clearly a case where leading 0 does not mean hex. -- This message was sent by Atlassian JIRA (v6.2#6252)
