Albert Lee commented on OPENJPA-719:
------------------------------------
In Turkish locale, there are 2 forms of letter 'i'. A dotted 'i' and a
non-dotted 'i'. Java String.toLowerCase and toUpperCase perform the following
case transformation:
toLowerCase( dotted 'i' (0x69) ) -> dotted 'i' (0x69)
toUpperCase( dotted 'i' (0x69) ) -> dotted 'I' (0x130)
toLowerCase( non-dotted 'I' (0x49) ) -> non-dotted 'i' (0x131)
toUpperCase( non-dotted 'I' (0x49) ) -> non-dotted 'I' (0x49)
toLowerCase( non-dotted 'i' (0x131) ) -> non-dotted 'i' (0x131)
toUpperCase( non-dotted 'i' (0x131) ) -> non-dotted 'I' (0x49)
toLowerCase( dotted 'I' (0x130) ) -> dotted 'i' (0x69)
toUpperCase( dotted 'I' (0x130) ) -> dotted 'I' (0x130)
In PCEnhance ( and most other OpenJPA code ), String.toUpperCase and
toLowerCase are used regardless of this particularity, which translated the
replaceIntField (and other variations of this method) to replace�ntField. Hence
the observed exception.
In this scenario, java fields and methods used for Reflection must not be
locale sensitive, hence toLowerCase/toUpperCase(Locale.ENGLISH) should be used
instead.
There are other use cases in OpenJPA that should also consider to be locale
insensitive, e.g. SQL reserved words should also use Locale.ENGLISH when
toUpperCase/toLowerCase is called.
