You are correct... but this is a pretty bad situation for our application.
Example:
This envelope:
GeneralEnvelope ge = new GeneralEnvelope(2);
ge.setRange(0, -150, -120);
ge.setRange(1, 20, 70);
returns a projected envelope of:
[-160.817 12.508 , 176.101 72.81]
which is clearly VERY wrong (far, far too east) -- almost looks like the sign got swapped on the calculation for the 176
However this envelope (only 10 degrees more north) looks like it might be correct:
GeneralEnvelope ge = new GeneralEnvelope(2);
ge.setRange(0, -150, -120);
ge.setRange(1, 30, 70);
Projected envelope: [-178.617 23.017 , -110.253 72.81]
Is there no way to project a coverage that is close to the equator/poles/prime meridian?

Try to restrict the image a little bit away from the pole, for example 89°N. Not all projection
behave well at the pole. For example for a Mercator projection, you can get infinite value toward
east or west.
