NPE when showing truffle expansions

[Stefan Marr]

Hi:

There seems to be an issue with static methods, apparently, the current check in place is not sufficient to guard for non-existing receivers.
The following patch seems to help:

diff --git a/graal/com.oracle.graal.truffle/src/com/oracle/graal/truffle/TruffleExpansionLogger.java b/graal/com.oracle.graal.truffle/src/com/oracle/graal/truffle/TruffleExpansionLogger.java

         }
 

Best regards
