This seems like a bit of abuse of `$(MODULE_SRC)`. I thought we had a macro to
get the proper source path for another module, but if we do, I cannot find it
now.
If you feel up for it, I'd encourage you to change this to:
Suggestion:
TZ_DATA_DIR := $(call FindModuleSrc, java.base)/share/data/tzdata
and add
################################################################################
# Find source dir for module
# Param 1 - module name
FindModuleSrc = \
$(TOPDIR)/src/$(strip $1)
at a suitable place in `Utils.gmk`.
Otherwise, just replace it with:
TZ_DATA_DIR := $(TOPDIR)/src/java.base/share/data/tzdata
