Not able to build jdk8/jdk8 (GenStubs.java:204: error)

[Mahesh Pujari]

Hi,
 I tried to build jdk8/jdk8 (with latest update, platform windows, build using cygwin), and I ended up with below compilation error:

--------------------------CONSOLE START----------------------------------

Building OpenJDK for target 'all' in configuration 'windows-ia32-normal-clientANDserver-release'

            tree.docComments = Collections.emptyMap();
                                                   ^

  where K,V are type-variables:

    V extends Object declared in method <K,V>emptyMap()

make[1]: *** No rule to make target `all', needed by `default'.  Stop.
Makefile:217: recipe for target `langtools' failed
make: *** [langtools] Error 2
--------------------------CONSOLE END----------------------------------

Seems like its coding error, I had to assign tree.docComment to null to make a successful build.


thanks and regards,
