I have JDK_HOME set to j:
When trying to start debug session on any of my programs I get:

java.lang.ArrayIndexOutOfBoundsException: -1
at org.eclipse.core.runtime.Path.segment(Path.java:855)
at org.eclipse.jdt.internal.launching.StandardVMDebugger.prependJREPath(StandardVMDebugger.java:374)

at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121)

This works fine when I set java to point to c:\java1.6_20 instead of j:
so that line: 
    jrepath.segment(jrepath.segmentCount()-2).equals(JRE)

in StandardVMDebugger.java does not throw

Reproducible: Always

Steps to Reproduce:
1. subst J: C:\jdk1.6.0_20 
2. set path to use j: instead of C:\jdk1.6.0_20
3. point eclipse to JDK of j:
4. Run any debug session.
