Thanks Alexeev,

I was able to get the profiler to work but only with
the following combination:

1. 3.3.x of Eclipse
2. 4.4.0.3 with all the tools (194MB Download)
3. Disabling any 1.6 unique code (painfull)
4. Compiling using 1.5.0_14 Sun jvm
5. Runtime 1.5.0_14 Sun jvm (have not trired 1.6.0_0X)

This took a couple of nights to run. My concern over
all of this is the lack of support for 1.6. As you can
tell if one needs to use 1.6 featues they can not do
this and this has been a known problem for several
years and Java is going to be a version 1.7 probably
by the end of the year. The TPTP package has very good
features but will probably not be usable in the next
year for development as companies move to 1.6 like
mine has.
Is there any plan to fix the attribute issue that is
related to jvmti and prevents developers from
compiling using 1.6 and TPTP?

I only found this news group when looking for TPTP
support. I will look at the other one you mentioned. I
will continue this discussion there.

Regards,
Tony

I am not aware of any issues with profiling Java 1.6 classes with the
new TPTP JVMTI Profiler. There is one outstanding issue regarding the
StackMapTable attribute
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=148629), but it occurs
only when you force the JVM to use the new Java 6 verifier (not the
default behavior).

My guess is that the problem you encountered is not related to Java 1.6
at all but to some configuration issue. If you can post more information
about the problem (exact configuration, usage scenario and exact error
message you get) we can provide more help.

This is in plan for 4.5, but as I said we do not prevent developers from
compiling 1.6 classes, and our profilers can successfully handle these
class files

This group is the best place to ask questions about TPTP. Please
continue to post your questions here.

Thanks,
Asaf
