As a software developer, in some cases, we have to work on software which is already aged.
Sometimes, you have also restrictions on a software collection to work with not
so "state of the art" technology.
Why does IntelliJ IDEA does not support OpenJDK 6?
A suggestion is made to use Oracle Java or a newer OpenJDK.
But, that is a risc, with aged software (above the things I have
to change in the sources), which I don' like to take now in the beginning
of the development for a new requirement.
