Regexpr from java not working in SQL

Question

Hello I have a complicated regexpr coming from java but when I try to use it with oracle RGEXPR_SUBSTR, it's seems to be buggy as I'm not having all the result (only partial)
Here is my regexpr for oracle and below the Java version
Oracle version:
^([A-Z0-9]{3})(\d{4,6})([A-Z]{2})(\d{2})\-(\d{2})([A-Z]{2})(?:\-(GA|CA|DEC|INFR|INF|CAC|DECC)?(\d{1,3})?)?(?:\-(\d{2})?((?:C|A|R|FIN|PC|APC|APCFIN|DEF|VO)+[0-9]*)?)?(?:\-(AV|CP|D|LP|NI|OJ|PF|PV|RA|RAS))?(?:\-(\d{1,}))?(?:\-([^\s]{1,}))?\-(OR|ORAN|RELU|TR|TRAN)(\.\w*)?$Java version
^([A-Z0-9]{3})(\\d{4,6})([A-Z]{2})(\\d{2})\\-(\\d{2})([A-Z]{2})(?:\\-(GA|CA|DEC|INFR|INF|CAC|DECC)?(\\d{1,3})?)?(?:\\-(\\d{2})?((?:C|A|R|FIN|PC|APC|APCFIN|DEF|VO)+[0-9]*)?)?(?:\\-(AV|CP|D|LP|NI|OJ|PF|PV|RA|RAS))?(?:\\-(\\d{1,}))?(?:\\-([^\\s]{1,}))?\\-(OR|ORAN|RELU|TR|TRAN)(\\.\\w*)?$I simply changed double backslashing \\ to simple backslashing \
Is my conversion wrong ?
Here are some test values

Hi,
Sorry, I can't understand your message.
Whenever you post code or formatted text on this sit, type
{code}
(small letters only, inside curly brackets) before and after sections of formatted text, to preserve spacing, and to keep brackets (which are common in regular expressions) from being treated as markup.
Format and coimmnet your code. For example:
SELECT  REGEXP_REPLACE ( '&txt'
                 , '(^|[^t[:blank:]|[:space:]])'     ||     -- \1 = Begining or some character other than t or space
                       '([[:blank:][:space:]]*)'     ||     -- \2 =     optional space
                  '(create)'               ||     -- \3 = 'create'
                '[[:blank:][:space:]]+'     ||     --      at least 1 space
                '(materialized)'               -- \4 = 'materialized'
                 , '\1\2\3 OR REPLACE /*ADDED*/ \4'
                 , 1
                 , 0
                 , 'i'
FROM    dual;Not everyone is familiar with regular expressions in Java. Can you explain what you code is supposed to do?
Why did you double the \ characters?
Use {code} tags around the output, too, so that people can tell what's in each column.
Are the results in the Java column correct?
