+Subject: [PATCH] Separate addPropertyAliases in two methods
+
+The quantity of data used to generate addPropertyAliases creates a big
+method, that is too big for java and results in "error: code too large".
+This is most likely due to added data between the expected version of
+icu and the actual version of icu in Guix.
