Error when getting key from KeyStore (java) -


i'm facing weird error. error started happen today, working on friday, , nothing changed, @ least nothing know.

i have simple keystore store key encrypt data. testing created separate application handle this. code:

public static void main(string[] args) {      properties prop = new properties();     try {         prop.load(new fileinputstream("./security/security.properties"));         string ksfile = prop.getproperty("ksfile");        string kspassword = prop.getproperty("kspassword");        string keyalias = prop.getproperty("keyalias");        string keypassword = prop.getproperty("keypassword");        prop.getproperty("carddataencryptionkey");         keystore ks;        ks = keystore.getinstance("jceks");         fileinputstream fis = null;        fis = new fileinputstream(ksfile);         ks.load(fis, kspassword.tochararray());          // symmetric        char[] keychararray = keypassword.tochararray();        protectionparameter proparam = new keystore.passwordprotection( keychararray );         keystore.entry entry = ks.getentry( keyalias, proparam );        secretkeyentry aeskey = (keystore.secretkeyentry) entry;                  aeskey.getsecretkey();          fis.close();      } catch (exception e) {         e.printstacktrace();     } }

code basic , open keystore configured in security.properties. problem i'm getting error in following line:

       keystore.entry entry = ks.getentry( keyalias, proparam );

i repeat wasn't happening, started suddenly. file ok, paths ok, file opened, when try keyentry, i'm getting numberformatexception, don't have clue if what's going on. error stack trace:
