Mathematica uses its own Java embedded in the installation directories, 
so the main Java on your machine is not relevant unless you are 
compiling Java code for use with J/Link. Mathematica 7 uses Java 6.

Do use a different context for your two notebooks (when things work OK).

The problem is that your variable dsol is shared by the two calculations 
- so one changes its value, which triggers the other into action.....

I solved it my using a Module to localise dsol:

Manipulate[
  Module[{dsol},
   dsol = DSolve[{k1 k2 b[t] == k1 b'[t] + b''[t], b[0] == b0,
      b'[0] == bp0}, b[t], t];
   Plot[Evaluate[b[t] /. dsol], {t, 0, 10}, PlotRange -> All]], {k1,
   0.1, 10}, {k2, 0.1, 10}, {b0, 0.1, 10}, {bp0, 0.1, 10}]
