hi Harold,
The code looks fine, I just have a question and tiny quibble:
#1. This comment:
189 // Return true if property starts with "jdk.module." and its ensuing chars match
190 // any of the reserved module properties.
191 // property should be passed without the leading "-D".
192 bool Arguments::is_internal_module_property(const char* property) {
about “-D” refers to the property expected by "Arguments::is_internal_module_property” method, not how the user passes it to the VM?
#2. The only tiny quibble would be to put:
200 matches_property_suffix(property_suffix, PATCH, PATCH_LEN) ||
right after
197 matches_property_suffix(property_suffix, ADDREADS, ADDREADS_LEN) ||
to match their declaration order:
170 #define ADDREADS "addreads"
171 #define ADDREADS_LEN 8
172 #define PATCH "patch"
173 #define PATCH_LEN 5
cheers
