Felix Müller commented on LANG-462:
-----------------------------------
Seems that I should have installed a pure JDK 5 on my machine and run the maven
build with java-1.5 profile first: As you can see on the CI server, I forgot
one java 6 dependency. I also fixed this with the next attached patch.
With the use of JDK 5 the FastDateParser has a really curious problem. One of
the test patterns causes the parser to end up in an infinite loop. I debugged
through the code: In JDK 5 the Pattern.compile method seems to be buggy. You
can reproduce the problem when you look into FastDatePrinterTest line 115/116
(with the merged patch) and run the test class FastDateFormat_PrinterTest. To
secure the test I added a timeout of 20 seconds.
The attached patch consists of the fully Java 5 compatible classes (I
successfully run "mvn clean package -Pjava-1.5"), some minor clean up and the
semi-fixed test.
I don't know if it would be good to release a class where we cannot say under
what circumstances it will crash or end up in an infinite loop.
