MessageBuffer unable to parse java.specification.version for java 10

[arnaudroger]

java.specification.version for java 10 is "10"
MessageBuffer is expecting a '.' and will then not use unsafe even if available
I suspect the same is true for 9 and 11.
a workaround is to override the property on the command line

-Djava.specification.version=1.10

It's fixed in 0.8.19.
