Thank you for quick answer.
However. .not exactly the one I hoped for:(
Generally - IMHO the CreateSecurityJars.gmk is never used to generate policies, only the
GendataPolicyJars.gmk is used for that.
Thats why my unhappy patch is here.
In one way or another - the GendataPolicyJars should be removed, or he lines regarding policies'
jars from CreateSecurityJars should e removed (second is probably more correct way, If you light on
green light to this patch, I will remove the lines from CreateSecurityJars and test)
jmod? jlink? Crap :) The policies had remained simple jars, and are nothing but copied into image.
I was looking to Images.gmk pretty much, and found quite a usages of JLINK_TOOL but found much less
looking to it,, not its usages nor it documentation did not resolved how the jars get to the old
good.../lib/security/ directory. It does not have much to do with modules....
And even if the jlink tool should be responsible for copying the jars (which is pretty obfuscated
way) then perhaps it should keep time stamps? (just thought)
I'm much much more troubled about way how the GendataPolicyJars and CreateSecurityJars are mixed up:(
Again, thank you very much for looking into it!
