[rfc][icedtea-web] Fix accessing Java array elements from Javascript

[Jie Kang]

Hello,

Marcin Cieslak has taken the time to create a fix for a long-standing problem in Icedtea-Web where attempting to set/get Java array elements from Javascript fails. [1]

[1] http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=1298


The reproducers relevant to this fix are:

simple/JToJSString

These reproducers tests on F21 with OpenJDK 7 and HEAD patched are now passing for me. These aren't in 1.5.x


simple/JSToJSet

These reproducers are still failing. On further investigation, the reproducer itself is not working correctly. A fix is needed here and work is in progress.

I have created a simple reproducer that mimics AppletJSToJSet_intArrayElement_Test and it passes. This is attached as: itw-js-int-array-test-1.patch. This reproducer passes on both 1.5 and HEAD.


I think a backport to 1.5.x would also be great. The two patches for HEAD and 1.5 are attached as: itw-js-array-HEAD-1.patch and itw-js-array-1.5-1.patch.

Thoughts?


Thank you again Marcin!


Regards,
