Egor Ushakov updated GROOVY-7647:
---------------------------------
Description:
Try to debug the code:
{code}
boolean boolVar = false; //line 15
if (boolVar) { // set breakpoint here and step over //line 16
print "ok"; //line 17
} // end of file //line 18
{code}
It steps over to the line with print even though it is not executed.
Seems that compiler does not generate line info for the last block (line 18):
{code}
public java.lang.Object run();
descriptor: ()Ljava/lang/Object;
flags: ACC_PUBLIC
Code:
