I found a flag, but it was encrypted! Our systems have detected that someone has successfully decrypted this flag, and we stealthily took a heap dump of the program (in Java). Can you recover the flag for me? Here's the source code of the Java program and the heap dump: https://mega.nz/#!rHYGlAQT!48DlH2pSZg10Ei3f-Ivm7RoNBbV16Qw0wN4cWxANUwY
