Description Bernd Hufmann CLA 2016-07-18 10:25:54 EDT 
I get a NullPointerException in the I/O analysis of a LTTng 2.7 trace. 

Exception in thread "Input Output Analysis Event Handler" java.lang.NullPointerException
	at org.eclipse.tracecompass.internal.analysis.os.linux.core.inputoutput.handlers.SysExitHandler.handleEvent(SysExitHandler.java:67)
	at org.eclipse.tracecompass.internal.analysis.os.linux.core.inputoutput.InputOutputStateProvider.eventHandle(InputOutputStateProvider.java:125)
	at org.eclipse.tracecompass.tmf.core.statesystem.AbstractTmfStateProvider$EventProcessor.run(AbstractTmfStateProvider.java:213)
	at java.lang.Thread.run(Thread.java:745)
Comment 1 Bernd Hufmann CLA 2016-07-18 10:47:56 EDT 
Looking at the trace I noticed that syscall_exit_mmap2 doesn't have the field ret. This causes a NullPointerException in SyscallExitHandler.
