[8udev] Request for approval for backport of JDK-8064857: javac generates LVT entry with length 0 for local variable

[Vicente-Arturo Romero-Zaldivar]

Hi,

Please approve the backport of JDK-8064857 from 9 to 8udev repo.

JDK9 bug entry: https://bugs.openjdk.java.net/browse/JDK-8064857
JDK8 bug entry: https://bugs.openjdk.java.net/browse/JDK-8068546
changeset: http://hg.openjdk.java.net/jdk9/jdk9/langtools/rev/3bdbc3b8aa14

The code applies cleanly, except for the paths differences due to 
modules in 9.

Thanks,
Vicente
