If and elseif block empty then condition change to normal statement.

[hardiknai]

hello,
I am using java decompiler version jd-gui-windows-1.4.0.
I have an issue in same code compiled using same JDK 1.5. but getting different decompilation.
If and else if block empties then condition change to the normal statement.
Actual Code : if (!e.isTemporary()) {}

1. e.isTemporary(); it not right then how can i trust.
2. if (!e.isTemporary()) {} it right but.

Regards
Hardik Nai
