Well, the old result was wrong :)
In[1]:= $Version
Out[1]= 5.0 for Linux (July 10, 2003)
In[2]:= Integrate[(Log[a*x]/Sqrt[1 + x^2])*BesselJ[0, x], {x, 0, Infinity}] //InputForm
Out[2]//InputForm= BesselI[0, 1/2]*BesselK[0, 1/2]*Log[a]
In[3]:= N[% /. a->2]
Out[3]= 0.681436
In[4]:= NIntegrate[(Log[a*x]/Sqrt[1 + x^2])*BesselJ[0, x] /. a->2, {x, 0, Infinity}, Method->Oscillatory]
Out[4]= -0.316503
