The disassembler plugin uses certain JVM functions to display information about values (especially managed pointers) embedded in the disassembled code. Unfortunately, in the product build, many of these functions are stubbed out, and produce no output. This leaves puzzling blank spaces in the disassembled code produced by the JVM. This is true in the product build, which is the default and often the only build available.

Fortunately, it is a simple matter to move those functions into the product build. There are not many of them, and they are not complex, so the footprint impact is minimal.
