when the security provider can not be verify creating of new ciphers is very slow

a typical stacktrace is

an error occurs in javax.crypto.Cipher. and the SecurityHelper creates the Cipher without the isCallerTrusted(). the indication that the isCallerTrusted() fails is that the checks happens again and again but positiv results get cached by the JceSecurityManager.

reverse the order and first use the constructor without isCallerTrusted() first and fallback on the other constructor is OK. note both the constructors are protected or package private.
