RFR(XXS): 8214108: Incorrect Function parameter lists in some jtreg tests

[Simon Tooke]

Hello,

I'm not sure if this belongs in the serviceability group, but the tests
are for jvmti, so it seemed appropriate.
Please point me elsewhere if not.

Two tests define a ClassUnload() callback function with an incorrect
parameter,"jvmtiEnv jvmti_env", instead of "jvmtiEnv* jvmti_env".  

This will lead to an invalid cast warning on some compilers, but
currently has no impact on the tests as ex03t001 is disabled, and the
body of the other ClassUnload() is empty. These issues were found by
compiling with GCC 8.1.

Bug: https://bugs.openjdk.java.net/browse/JDK-8214108
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/stooke/JDK-8214108/01/webrev/

For what it's worth, ex03t001 does pass if enabled, but I don't know if the test is correct at this point; it's been disabled for a while.

Please let me know what you think,

Thanks,
-Simon
