paths seem to not get expanded for the `sources` field in `referencedLibraries`

[hekar-lab]

When using the field sources in java.project.referencedLibraries expressions that should be expanded (i.e. ~ and ${ENV_VAR}) seem to not work properly.

Additional context

• The expansions work properly for the include field.
• I have tried to use absolute paths with no expansion and it works as intended.
• As the expansion method seems to be the same for include and sources, I'm guessing that something goes wrong in how the JSON gets converted to a Java Object.
