+# DP: Fix hotspot build system for GNU make 4.0.
+
+Description: Fixes a bug in adjust-mflags.sh that breaks the hotspot build
+ with GNU make 4.0. The adjust-mflags.sh script attempts to replace
+ the -j parameter but it corrupts other parameters containing the character 'j'.
+ make 4.0 is more strict and returns an error in this case.
+ 
+ For example:
+ 
+     -I/home/ebourg/openjdk8/make/common
+ 
+ is transformed into:
+ 
+     -I/home/ebourg/open -j2 -dk8/make/common
+ 
+ This error is caused by this sed expression:
+ 
+     s/ -\([^ 	][^ 	]*\)j/ -\1 -j/
+ 
+ This expression splits a set of concatenated options containing the 'j' character:
+ 
+     -abcdefghijkl  -->  -abcdefghi -jkl
+ 
+ But it breaks the -I parameter which is followed by a path that may contain 'j'
+ (and this is often true when building open*j*dk)
+ 
+ The fix consists in ignoring the concatenated options if '/' is found.
