BCTLS 1.61 Potential Issue

Hello Everyone,

I was just testing the bctls-jdk15on-161 and encountered the following 
problem.

When making a call to the SignatureAndHashAlgorithm class before having 
used the TlsUtils class a NulPointerException is thrown. To replicate 
just make a call to

SignatureAndHashAlgorithm signatureAndHashAlgorithm = new 
SignatureAndHashAlgorithm(HashAlgorithm.sha1, SignatureAlgorithm.rsa);

without any other BC calls before it. 


This has to do with the fact that the static objects in 
SignatureAndHashAlgorithm use the class constructor that calls TlsUtils 
and parts of the static initialization of TlsUtils lead to the use of 
static SignatureAndHashAlgorithm Objects that have not yet been initialized.

When a call to the TlsUtils class is made first, then there is no error.

I hope the information helps.

With Regard,
Stathis
