--------------------------------------
Summary: Replace Jakarta ORO by java.util.regex
Key: OFBIZ-7926
URL:
https://issues.apache.org/jira/browse/OFBIZ-7926 Project: OFBiz
Issue Type: Improvement
Components: framework, product
Affects Versions: Trunk
Reporter: Jacques Le Roux
Assignee: Jacques Le Roux
Fix For: Upcoming Branch
At OFBIZ-5395 I discussed with Adrian the possibility to replace Jakarta ORO by java.util.regex. At this time, based on arguments given by
http://tusker.org/regex/regex_benchmark.html in a bottom comment I stated
bq. ORO is 6 times faster than Java 1.6 regex (see link above). That's why I want to change the Java regex usage to ORO in OFBiz when relevant and possible (ORO has not all the features of Java regex). No needs to worry about it, it's fast and reliable. Anyway, If ever in the future we want to move to Java regex it's not a big deal. I saw you commited PatternFactory.java, I will have a look at the rest when I will get a chance.
More recently by chance I stumbled upon
http://www.javaadvent.com/2015/12/java-regular-expression-library-benchmarks-2015.html and in a last comment at OFBIZ-5395 I wrote (shortened)
bq. Just an update about "Java Regular Expression Library Benchmarks" in 2015, Tusker was in 2010!
So when you read the resuilt of the "Java Regular Expression Library Benchmarks" you can see it's time to switch from ORO. I'll have though to carefully revisit the end of OFBIZ-5395. IIRW no concurrency issue should be expected, they were removed by concurrency OFBIZ-5395.
