I define a com.dfs.test.ui.app1.contexts.window on top of context org.eclipse.ui.contexts.window
<extension
point="org.eclipse.ui.contexts">
<context
description="DFA App1 Window Context"
id="com.dfs.test.ui.app1.contexts.window"
name="DFA App1 Window Context"
parentId="org.eclipse.ui.contexts.window">
</context>
</extension>

I bind key M1+S on context com.dfs.test.ui.app1.contexts.window
<extension
point="org.eclipse.ui.bindings">
<key
commandId="com.dfs.test.command1"
contextId="com.dfs.test.ui.app1.contexts.window"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
sequence="M1+S">
</key>
</extension>

I activate the context when our perspective is activated and deactive the context when out perspective is deactivated as following:
final IWorkbenchWindow workbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (workbenchWindow != null) {
workbenchWindow.addPerspectiveListener(new PerspectiveAdapter() {
IContextActivation ctxAct = null;
public void perspectiveActivated(IWorkbenchPage page,
IPerspectiveDescriptor perspective) {
IWorkbench workbench = PlatformUI.getWorkbench();
IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
IContextService ctxService = (IContextService) window.getService(IContextService.class);
ctxAct = ctxService.activateContext("com.dfs.test.ui.app1.contexts.window");
super.perspectiveActivated(page, perspective);
}

public void perspectiveDeactivated(IWorkbenchPage page,
IPerspectiveDescriptor perspective) {
super.perspectiveDeactivated(page, perspective);
}

public void perspectivePreDeactivate(
IWorkbenchPage page,
IPerspectiveDescriptor perspective) {
if( ctxAct != null ){
ctxAct.getContextService().deactivateContext(ctxAct);
}
super.perspectivePreDeactivate(page, perspective);
}

});
}

all of above the code runs fine without any error. But after our perspective is deactivated, the context is still active. I see the ctxAct.getContextService().deactivateContext(ctxAct); is called without any error in perspectivePreDeactivate(). Why is the context not deactivated?

You can open a bug at https://bugs.eclipse.org/bugs against Eclipse Platform UI

If you attach a little plugin with your code in it, they can debug it.
