By saving as Java (after "Reset History") and comparing (gvimdiff) against an earlier version, I found that the following lines mentioning "sol2" appeared in the Java source:

...
model.batch("p1").feature("so1").set("psol", "sol2");
...
model.sol().create("sol2");
model.sol("sol2").study("std1");
...

Removing them, deleting the .run() calls and compiling as usual, everything worked normally.

The moral of the story is that if you create a solution, you'll be hit with a "Solution not initialized" error.
