Why applications compiled with DTS wont load libstdc++ and libgcc_s libraries for DTS?

Issue

• We have developed some c++ dynamic libraries and compiled under Red Hat Developer Toolset 4 using "scl enable devtoolset-4" command with gcc 5.3.1 version.
• These libraries are used by a java application which dynamically loads them on startup. The problem is that, when the java process starts, we look the process memory mappings in "/proc/pid/smaps" and find out that the old gcc and stdlib library versions are loaded. We tried to use the command "source scl_source enable devtoolset-4" before starting the java process, but result is the same.
• Could you please suggest any solution? The target is: library should be compiled under 5.x version of c++ and appropriate libraries should be loaded during the java application load. Here is some output from the smaps:
