compilation

Trying to upgrade to JDK8 on a big project, compilation goes really slow on JDK8 compared to JDK7. Running the compiler in verbose mode, JDK8 compiler stops at a big generated converter class(Mapping) for entities from server to client. The converter methods in several cases call other converter methods from the same Mapping class. As a workaround tried to split the Mapping file into multiple files. This visibly improved performance when only compiling the Mapping class or it's containing project(projectA). But compile time was very slow for other projects which invoke converter methods from

Aren't modern compilers smart enough to be able to generate a code that is fast and safe at the same time? Look at the code below: std::vector<int> a(100); for (int i = 0; i < 50; i++) { a.at(i) = i; } ... It's obvious that the out of range error will never happen here, and a smart compiler can generate the next code: std::vector<int> a(100); for (int i = 0; i < 50; i++) { a[i] = i; } // operator[] doesn't check for out of range ... Now let's check this code: std::vector<int> a(unknown_function()); for (int i = 0; i < 50; i++) { a.at(i) = i; } ... It can be changed to such equivalent: std:

Update I got this working. How I am not sure. I did no config changes at all. What I did was: Modify Dialog in frameworks/base/core/java/android/app . Went to my root ( /path/to/source/ ). Then I did mmm frameworks/base/ . Everything worked. Then I tried exactly what I had already tried below: Modify ScrollView (I actually never said which file I was modifying) in frameworks/base/core/java/android/widget . I ch 'ed to frameworks/base/core/java/android/widget . Then I did mm . This time I had no errors like before when the files were removed. Now it just works. Maybe this was some caching or
