Impossible to do an update:

* @Impossible de mettre à jour TXM : java.lang.NullPointerException: Cannot invoke "org.eclipse.swt.widgets.Shell.getDisplay()" because the return value of "org.eclipse.equinox.internal.p2.ui.sdk.PreloadingRepositoryHandler.getShell()" is null@

h3. Solution

The bug is not systematic -> we need to find when "org.eclipse.equinox.internal.p2.ui.sdk.PreloadingRepositoryHandler.getShell()" is null

Also log system broken:

* @SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".@

h3. Solution

The slf4j.api is looking for an implementation of org.slf4j.impl.StaticLoggerBinder and :
* does not find one
* OR failed to instanciate it

Adding one of the StaticLoggerBinder implementation jar to the "org.txm.rcp" libs does not fix the problem: slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar

Adding the org.slf4j.api to the dependant plugins of org.rxm.rcp does not fix the problem.
