[OpenJDK 2D-Dev] RFR: 8250755 Better cleanup for jdk/test/javax/imageio/plugins/shared/CanWriteSequence.java

[Sergey Bylokhov]

Hello.
Please review the fix for jdk/client.

Bug: https://bugs.openjdk.java.net/browse/JDK-8250755
Fix: http://cr.openjdk.java.net/~serb/8250755/webrev.00

The test in question creates two temp files. One of them properly cleaned after
http://cr.openjdk.java.net/~jdv/8183349/webrev.02/test/javax/imageio/plugins/shared/CanWriteSequence.java.sdiff.html

But there is another one created by the ImageOutputStream, so the ImageOutputStream should be closed
to delete this temp cache file.
