Below SharedBuffer unit test cases are written with fixed segment size assumption. But after JDK-8187483, the behavior is changed to use variable size segments (https://trac.webkit.org/changeset/215686/webkit) .

Hence We need to remove the below unit test cases as they are invalid now:

1) modules/javafx.web/src/test/java/test/com/sun/webkit/SharedBufferTest.java

testGetSomeDataFirstSegmentLastTenBytesWithTruncation()
testGetSomeDataInteriorSegmentLastTenBytesWithTruncation()
testGetSomeDataFirstSegmentWithTruncation()
testGetSomeDataInteriorSegmentWithTruncation()
testAppendThreeSegments()
testAppendThreeSegmentsPlusSegmentPlusTenBytes()
testAppendTenBytesPlusSegmentPlusThreeSegments()

2) modules/javafx.web/src/test/java/test/com/sun/webkit/SimpleSharedBufferInputStreamTest.java

testRead3FirstSegmentLastTenBytesWithTruncation()
testRead3InteriorSegmentLastTenBytesWithTruncation()
testRead3FirstSegmentWithTruncation()
testRead3InteriorSegmentWithTruncation()
testRead3StandardUse()
testSkipOneByte()
testSkipTenBytes()
testCloseBeforeSubsequentRead()
testDoubleClose()
