8241370: Crash in JPEGImageLoader after fix for JDK-8212034 #154

This is a regression of JDK-8212034.
When image is loaded in WebView usinga url, WebView attempts to load a image frames with partial image data. This was implemented under,
JDK-8153148 -> WCImageDecoderImpl.addImageData() -> calls loadFrames() with partial image data.

Call to jpeg_read_header() may fail when the partial image data has incomplete header information.

In the given case the jpeg_read_header() call fails and code execution flow enters the 'if (setjmp(jerr->setjmp_buffer)) {}' block and results in call to disposeIIO(env, data);, which in turn calls imageio_dispose. This will free cinfo->err and set it to NULL, and the subsequent call to (*cinfo->err->format_message) crashes.

Verified All test run, Sanity tests with Ensemble app and Tested different web pages.
Added a test, The test passes with fix and causes a native crash without the fix.

The fix looks good. I can also confirm that the test fails (crashes) without your fix and passes with your fix.

The new test doesn't use Robot, so it should be moved to a package not underneath test.robot. For consistency with similar tests in, I recommend

I left a few other comments on the test.

@johanvos This is a simple enough fix that I don't think it needs a second reviewer. Feel free to review it if you like.
