             Summary: Broken master: Compilation errors in VSC++ 2013 and 2015
                 Key: REEF-1909
                 URL: https://issues.apache.org/jira/browse/REEF-1909
             Project: REEF
          Issue Type: Bug
          Components: REEF Bridge
            Reporter: Sergiy Matusevych
            Assignee: Julia


Our current master branch fails to compile with Visual Studio 2013 and 2015, giving the following error:
{code:none}
       "C:\projects\reef\lang\cs\Org.Apache.REEF.sln" (default target) (1) ->
       "C:\projects\reef\lang\cs\Org.Apache.REEF.Network.Examples.Client\Org.Apache.REEF.Network.Examples.Client.csproj" (default target) (24) ->
       "C:\projects\reef\lang\cs\Org.Apache.REEF.Bridge\Org.Apache.REEF.Bridge.vcxproj" (default target) (25) ->
       (ClCompile target) -> 
         InteropUtil.cpp(138): error C2146: syntax error : missing ';' before identifier 'JNIEnv' [C:\projects\reef\lang\cs\Org.Apache.REEF.Bridge\Org.Apache.REEF.Bridge.vcxproj]
         InteropUtil.cpp(138): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int [C:\projects\reef\lang\cs\Org.Apache.REEF.Bridge\Org.Apache.REEF.Bridge.vcxproj]
{code}
(e.g. see AppVeyor logs [here|https://ci.appveyor.com/project/ApacheSoftwareFoundation/reef/build/1974-master/job/i2chdmctv2w90dsi#L2985])

It looks like the earlier versions of VS (managed) C++ do not support {{thread_local}} keyword. We need to fix the code to make sure it compiles on all supported versions of Visual Studio.

The issue was likely introduced in [REEF-1895] (github pull request [#1385|https://github.com/apache/reef/pull/1385]).
