Resources part of the try-with-resources statement does falsely require a trailing semicolon about language-java

[MFKoelmans]

I found a hacky workaround: adding a semicolon before the closing parenthesis of the try. It is redundant there, but it fixes the highlighting of the following code.

The best way to implement this is to create a separate rule for try-with-resources, because currently the variable assignment rule waits for the ending semicolon before terminating.

Yeah, it isn't a normal assignment any way.
Normal assignment looks like this:

AssignmentExpression:
  ConditionalExpression 
  Assignment
Assignment:
  LeftHandSide AssignmentOperator Expression
LeftHandSide:
  ExpressionName 
  FieldAccess 
  ArrayAccess
AssignmentOperator:
  (one of)  =  *=  /=  %=  +=  -=  <<=  >>=  >>>=  &=  ^=  |=

The "Resource" from the try-with-resources statement dosen't support komplex assignments (+= etc.) for example.

Thanks for workaround! I managed to patch code for it to work:

This is hacky as well, however, passes all tests in master branch.

Are there any plans to merge this or fix the problem some other way?

[sadikovi]

There is an open pull request to fix this issue, but it needs to be revisited and rebased. Will get back to it soon.
