A DESCRIPTION OF THE PROBLEM :
When a Java argument file (@argument_file) contains a comment following immediately (no spaces) a value, then the parser behaves unexpectedly. If it cannot be fixed (due to maintaining backward compatibility), then please document these behavior.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use the following simple Java code as `test.javash`:

```
public class Main {
  public static void main(String[] args) {
    for (String arg: args) {
      System.out.println(arg + ": " + System.getProperty(arg));
    }
  }
}
```

and the following Bash script:

```
run_java() {
  echo "-- input"
  cat args
  echo "-- output"
  java @args --source 24 test.javash my_var1 my_var2 my_var3
  echo "-- end"
  echo
}

cat > args <<EOF
-Dmy_var1=value1 -Dmy_var2=value2#COMMENT
-Dmy_var3=value3
EOF
run_java

cat > args <<EOF
-Dmy_var1=value1 -Dmy_var2=value"2"#COMMENT
-Dmy_var3=value3
EOF
run_java

cat > args <<EOF
-Dmy_var1=value1 -Dmy_var2=value"2"#COMMENT
 -Dmy_var3=value3
EOF
run_java

cat > args <<EOF
-Dmy_var1=value1 -Dmy_var2=valu"e"2#COMMENT
-Dmy_var3=value3
EOF
run_java

cat > args <<EOF
-Dmy_var1=value1 -Dmy_var2=value2
-Dmy_var3=value"3"#COMMENT
EOF
run_java
```

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect all "-- output" parts to contain:
my_var1: value1
my_var2: value2
my_var3: value3
ACTUAL -
-- input
-Dmy_var1=value1 -Dmy_var2=value2#COMMENT

my_var2: null
my_var3: value3
