Server.Coldfusion.SupportedLocales includes unsupported locales

round tripping lsParseDateTime( lsDateTimeFormat(testDate)); only works with a few locales

I came accross this issue during experimentations and would like to complement some additional informations.

• The locales sr_BA_#Latn, sr_ME_#Latn, sr_RS_#Latn, ja_JP_JP_#u-ca-japanese, th_TH_TH_#u-nu-thai are Java Locales IDs. The locales given by server.Coldfusion.SupportedLocales are all English Locales DisplayNames from the underlying Java, with the exception of these 5 mentioned above (which are Locale IDs. Why? Maybe the corresponding displaynames had “,” and this would break the list server.Coldfusion.SupportedLocales?

• Because Lucee’s cfml setLocales() can have the Java DisplayName OR Java LocaleID passed as an argument, you can set them with it’s corresponding English DisplayNames as workaround/alternative.
  
  

That means that the issue could possibly be resolved by populating server.Coldfusion.SupportedLocales with all English DisplayNames of the Java Locales. For better illustration/proof run simple test template below testSetLocales.cfm. It outputs data with setting server.Coldfusion.SupportedLocales and java.util.Locales.getAvailableLocales() with DisplayName as proof.

If it comes to compability with ACF: ACF accepts ALL Locale IDs of Java.util.Locale.getAvailableLocales() and only a small set of DisplayNames. Lucee accepts all from both with exception of the 5 issued above. Thus it would be even better for compability reasons to make these work and then populate server.Coldfusion.SupportedLocaleswith Locale IDs and DisplayNames alltogether in Lucee.



for demonstration testSetLocales.cfm

I've added test case for this ticket, Lucee doesn't supports for following locales from #Server.Coldfusion.SupportedLocales#.

In below three locales were working fine while removed '#'

can you please make a testcase for this?

I've analyzed this ticket & confirmed the issue happened on latest version of lucee. We can able to setLocale from the server.coldfusion.SupportedLocales.
