JDK-8062923 - XSL: Run-time internal error in 'substring()'
Description
XSL substring(value,start, length) function incorrectly process the -Inf length values (the -Inf is treated as Inf). 
Consider the following xsl code snippet:
|<xsl:value-of select="substring('asdf',2,-1 div 0)"/>|
It should return:
||
But the result is:
|sdf|

Reopening, because the observed error differs from the error observed in JDK-8062923.

The root cause of this issue that negative length values shouldn't be processed by the substring() XSL function and the empty string should be returned. In such case this bug is a duplicate of 8062923.
