JVM selection not working [message #1689988]

Tue, 24 March 2015 16:32

I am using: "1.1.0 Build 997" under windows.

In the "Java 1.7+ VM" combo, I can not select any JVM.
I have tried the "Manage Virtual Machines..." button.
In the "Java Virtual Machines" dialog, when I use the "Search..." button and point to a folder were my JRE are, there is a "Progress Information" box, but the feature ends with "No new VMs found".

I am sure this was working with "Oomph 1.1.0 Build 991" and nothing has changed with my JVMs since then.

What can I do?
How can I debug this?

I have tried to remove {user home}/.eclipse/org.eclipse.oomph.jreinfo folder. By comparison the new one (created today) do not contains the two files "defaults.properties" and "infos.txt".

Thank you in advance for your help.

Jeremie,

I saw the following this morning:

Exception in thread "JRE Initializer" java.lang.NullPointerException
at
org.eclipse.oomph.setup.ui.wizards.ProductPage.refreshJREs(ProductPage.java:591)
at
org.eclipse.oomph.setup.internal.installer.InstallerDialog.refreshJREs(InstallerDialog.java:100)
at
org.eclipse.oomph.setup.internal.installer.InstallerApplication$1.run(InstallerApplication.java:85)

I've not seen this before and I don't see a recent commit that explains
why I see it only now. I think this problem is timing related as hinted
by the following comment in
org.eclipse.oomph.setup.internal.installer.InstallerApplication.run(IApplicationContext)

if (jresInitialized)
{
// TODO Do we need to make sure that this takes effect AFTER
the UI is visible?
installerDialog[0].refreshJREs();
}

The one time I saw this (with a NullPointerException breakpoint which I
always have enabled), the field was not actually null when the debugger
stopped here:

public void refreshJREs()
{
javaController.refresh();
}

But this was on a background thread while the UI initializes of course
on the UI thread. I'll need to speak to Eike the thinking here.

Please open a bugzilla... Perhaps after a few tries it would work
properly for you, but perhaps you hit this each time. You might check
your log in the installer's configuration folder. Perhaps delete all
the old ones to see what's in a new one...

Thank you for your answer. I have opened Bug 463056.

As you sugested, I have also attached my Log File.

I can also see a java.lang.NullPointerException at org.eclipse.oomph.setup.ui.wizards.ProductPage$6.jreChanged(ProductPage.java:284).
The previous exception is:

!ENTRY org.eclipse.oomph.jreinfo 4 0 2015-03-25 09:55:43.935
!MESSAGE no jreinfo.dll in java.library.path
!STACK 0
java.lang.UnsatisfiedLinkError: no jreinfo.dll in java.library.path
	at java.lang.ClassLoader.loadLibrary(Unknown Source)
	at java.lang.Runtime.loadLibrary0(Unknown Source)

	at org.eclipse.oomph.jreinfo.JREManager.determineOSType(JREManager.java:330)
	at org.eclipse.oomph.jreinfo.JREManager.<clinit>(JREManager.java:42)
	at org.eclipse.oomph.setup.internal.installer.InstallerApplication$1.run(InstallerApplication.java:79)

.

On my computer, the problem is reproducible.

Please tell me if I need to try something (like the clear log operation you suggested).

Jeremie,

Yes, after my other changes and updates I ran into this too. An
accidental commit that commented out fragments from several features
were at fault. As of build 1001, these problems should be gone again so
an update should pick those up.

Hi Ed,

Thanks for your effort. I have udpated to "1.1.0 Build 1001"

The NullPointerException is gone from the Log, but I still have:

!ENTRY org.eclipse.oomph.jreinfo 4 0 2015-03-25 12:21:07.874
!MESSAGE no jreinfo.dll in java.library.path
!STACK 0

	at org.eclipse.oomph.setup.internal.installer.InstallerApplication$1.run(InstallerApplication.java:77)

I still can not select any JVM.

Please download the installer from the main Eclipse site (Canada) until all the mirrors have picked up the new build
(can take up to 24 hours).

Cheers

Or update the own you've downloaded to pick up the 1001 build...

I downloaded the oomph-extractor-win64.exe from the "Developer Builds" download page, picking the canada mirror.

It is now working again. I will comment on the Bug 463040.

Side-question:
Does it mean that the "Install available updates" button in Oomph also depends on some random mirrors?

No, the updates use the update site and (I believe) if the artifacts
associated with that are mirrored, those random mirrors can/might be used.

The installer link itself also allows mirroring, but it might be the
case that the mirror does not yet have the same/recent version that's at
the main download site. That's the problem I ran into, but rather than
download and install again, I just did an update, and that picked up the
latest changes, which then worked correctly, finally...
