           Summary: Shark fails to catch java.lang.NullPointerException
                    using catch (Throwable e)
           Product: IcedTea
           Version: 6-hg
          Platform: all
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Shark
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: xerxes at zafena.se


Testcase:
cd openjdk/hotspot/test/compiler/6741738
javac Tester.java
java -Xcomp -XX:CompileOnly=Tester.foo Tester

Output:
Exception in thread "main" java.lang.NullPointerException: 
        at Tester.foo(Tester.java:39)
        at Tester.main(Tester.java:48)

Observations:
Changing the testcase to catch (Exception e) instead of catch (Throwable e)
makes Shark pass the testcase so it looks like shark are unable to catch
Exceptions using catch (Throwable e) despite the fact[1] that Exception are a
subclass of Throwable. [1] ref:
