Applet using JNLP failed to launch using requested JRE version even if the JRE requested is installed on the machine. FOr exmample install 6u18,1.4.2_20 and 1.5.0_22 on the machine and applets using JNLP with <j2se version=1.4.2*> and <j2se version=1.5*> will get launched using 6u18 only ignoring the 1.4.2_20 and 1.5.0_22 installed on the machine. If insecure baseline release from the 1.4.2 or 1.5.0 train is installed then after accepting the SSV pop-up applet is getting loaded with correct version of JRE

This is a regression since 6u15
Steps to reproduce:
-------------------
1) Install 6u18, 5u22 and 1.4.2_20 on the machine
2) Try to load the follwing applet

3) If all the applets get loaded with 6u18 then bug is reproduced

4) Remove 5u22 and 1.4.2_20 from the machine
5) Now install insecure version of JRE from the 1.4.2 and 1.5 train e.g. 1.4.2_18 and 1.5.0_18
6) Load the same applet in #2 again
7) Accept the SSV pop-ups , this time applets will get loaded using correct JRE versions i.e.
- 1st applet will get loaded using 1.5.0_18
- 2nd applet will get loaded using 1.4.2_18
- 3rd applet will get loaded using 1.6.0_18
