Problem

-- When using jre7 to launch some TrkAPiUA program, the following exception can appear:

ERROR Exception in thread "Thread-XX" java.lang.UnsatisfiedLinkError: /path/to/axway/Java/linux-x86/jre7_u51_64/lib/amd64/xawt/libmawt.so: libXrender.so.1: cannot open shared object file: No such file or directory

Resolution

- This happens because the libXrender.so library is a prerequisite for jre7. Solution is simply to install this library on the system (can be found in libxrender package).
