Launcher finds Sun VM instead of IBM VM on Windows. [message #656772] Mon, 28 February 2011 14:40 Go to next message

I have an IBM VM as my system VM (the IBM java.exe is in \windows\system32

When I start Memory Analyzer it uses the Sun VM instead. I think this is because org.eclipse.equinox.executable/library/win32/eclipseWin.c doesn't find a JRE/SDK directory for the java.exe, so goes straight to using registry keys to find the VM.

I know I could use -vm to chose a VM, but I think the launcher could do better. The simplest solution would be to use isSunVM() on the executable, and only use the registry keys if it is a Sun VM. Starting the java.exe otherwise for IBM VMs would be acceptable for me, though using the IBM registry keys and linking to java.dll would be even better.

Andrew,

The launcher has a JRE tab. By default it uses the same JRE you used to
run Eclipse itself, I think. But you can configure other JREs and use
those.

The problem occurs when running Memory Analyzer as an RCP product, not when launching Memory Analyzer from inside Eclipse.

The problem also occurs when running Eclipse without the -vm option.

Help->About->Installation Details->Configuration
shows the Sun VM even though the system VM is an IBM one.

Andrew,

If you really want something in the implementation to change, you'll
need to open a bugzilla and then wait very patiently.
