after a system update on my Debian Jessie system, I ran into problems with eclipse (Juno).

First, I got a broken JRE configuration. I had to create a new definition ( /usr/lib/jvm/java-7-openjdk-amd64/) to resolve this.

Since then I get errors in different situations mentioning some "iClasspathEntry":. For example when launching a single Java file with a main method:

An internal error occurred during: "Launching Path".

org.eclipse.jdt.internal.core.ClasspathEntry$AssertionFailedException: Path for IClasspathEntry must be absolute: 
	at org.eclipse.jdt.core.JavaCore.newLibraryEntry(
	at org.eclipse.jdt.internal.launching.JRERuntimeClasspathEntryResolver.resolveLibraryLocation(
	at org.eclipse.jdt.internal.launching.JRERuntimeClasspathEntryResolver.resolveLibraryLocations(
	at org.eclipse.jdt.internal.launching.JRERuntimeClasspathEntryResolver.resolveRuntimeClasspathEntry(
	at org.eclipse.jdt.internal.launching.RuntimeClasspathEntryResolver.resolveRuntimeClasspathEntry(
	at org.eclipse.jdt.launching.JavaRuntime.resolveRuntimeClasspathEntry(
	at org.eclipse.jdt.launching.AbstractJavaLaunchConfigurationDelegate.getBootpathExt(
	at org.eclipse.jdt.launching.AbstractJavaLaunchConfigurationDelegate.getVMSpecificAttributesMap(
	at org.eclipse.jdt.launching.JavaLaunchDelegate.launch(
	at org.eclipse.debug.internal.core.LaunchConfiguration.launch(
	at org.eclipse.debug.internal.core.LaunchConfiguration.launch(
	at org.eclipse.debug.internal.ui.DebugUIPlugin.buildAndLaunch(
	at org.eclipse.debug.internal.ui.DebugUIPlugin$

Also when opening the Java preferences, I get errors like this:

unable to create the selected preference page

Sometimes the JRE settings get lost, and I have to define them again.

However, when I repeat playing around then sometimes it works again.

What is going on here?
