Description

Hi all!

I faced with strange behavior in execute following simple java code:

public class Test
{
public static void main(String[] aoA_)
{

{ String jsS = "398203" + "24242424242424242424242424242424" + "32342342423423403030303031200625" + "124612234234002342342423445E949C" + "F45E000000000000000000000000022B" + "52342423423424242423423423383030" + "C234234234234234242348D952D859F2" + "00000000000000000000000000000000" + "00000000000000000000000000000000" + "00000000000000000000000000000000" + "00000000000000000000000000000000" + "234234234234234587CA50E92F18460F" + "2342342423424242342342E04C41ADA5" + "AFB1C424234234234234234234234234" + "E2341623404923479E2344822374DEC1" + "023419E2344B23343234323042304234" + "23402334223645123451234523040243" + "4568CC4546435624562456145464356E" + "234A2234123342344234423342242343" + "234FC234C235422343234E234423F423" + "123E451235964F56545624566456F455" + "105EC12391B23F11238123121313F45E" + "0132C10232C12F312283212631123433" + "A32321323333333363123123E5912353" + "A72340234F235422D9262E262B22F454" + "044ED4004F434F4149464E464E4C4455" + "0345303E53A45234523454354345A35E" + "34593C4513C45A356345534513503534" + "345DA3F45234553945634553245B3452" + "C456624056A4526A4567459645261465" + "45604056F451645D6045604536405645" + "4536456045260455624536B456845645" + "456F06450604506405646456554D6548" + "56373737356630567576657537506777" + "678067383637866738677896D7836F78" + "7899678B95789278A997892759708997" + "678696979467296F792679169767997A" + "67966729637926795679697669696797" + "679189F6979F7690679669D69A697696" + "5688568568E5618538A586568585685A" + "4574957F45724A576457045745747459" + "D4574570457B4574574574574574574B" + "45703045704570457040745745372457" + "45724957B4578450740574457F474751" + "3346F43E46324634FA43642346632636" + "34610034633F46D34623164346436432" + "324023148234D2934B273452C202CF22" + "2234CC23432C34F23F4D234923742534" + "2345644A424D192340225226303B3F34" + "34520C53A45E345E3546396675675670" + "345304500034503501001D2301211101" + "234F043437"; System.out.println("1:\{" + jsS.length() + "}

[0x" + jsS + "].");
System.out.println("2:{" + jsS.length() + "}[0x" + jsS + "].");
}
}
}

It takes 1-3 seconds to execute in Netbeans whereas executes instantly in command line on the same machine. Sometimes the execution time of this code grows up to 9 seconds. It depends of data in string value. Various data with the same length takes different time to execution. It is very strange to me.

Log of code execution:
