RFR: JDK-8189796: Incorrect end position for missing statement

[Jan Lahoda]

Hi,

Consider code like:
{
      if (true)
}

(i.e. missing statement after "if"). The if statement will get parsed as 
"if (true) (ERROR);", which appears OK, but the end position for 
"(ERROR);" and "(ERROR)" is not set. In addition, due to this, the end 
pos of the error/diagnostic produced is -1.

Bug: https://bugs.openjdk.java.net/browse/JDK-8189796
Proposed patch: cr.openjdk.java.net/~jlahoda/8189796/webrev.00/

Thanks,
      Jan
