Bug#779798: openjfx: FTBFS error: conflicting declaration 'typedef int32_t UChar32'

[Emmanuel Bourg]

Thank you for the report Andreas, this is a side effect of the icu
support recently enabled in libxml2 (#776254). I fixed it today in
openjfx/8u40-b25.

Bug#779798: openjfx: FTBFS error: conflicting declaration 'typedef int32_t UChar32'

[Andreas Cadhalpun]

Source: openjfx
Version: 8u20-b26-3
Severity: serious

Dear Maintainer,

This can also be seen in the reproducibility rebuild [1].
