RFR: 8266187: Memory leak in appendBootClassPath() [v2]

[Wang Huang]

> Dear All, 
>     I find a memory leak in `appendBootClassPath()`
> https://github.com/openjdk/jdk/blob/75a2354dc276e107d64516d20fc72bc7ef3d5f86/src/java.instrument/share/native/libinstrument/InvocationAdapter.c#L950
> * we malloc `resolved` from resolve(parent, path)
> * we use `resolved` in line 951 
> * we don't free() this memory after using.
> 
> I think we can fix this bug by adding a free() after line 951 as my commit.
> Thank you for your review. Any suggestion is welcome.

> Yours ,
