Several PKCS11 tests occasionally fail on Solaris SPARC servers running 11.1 or earlier:

    sun/security/pkcs11/Signature/ReinitSignature.java
    sun/security/pkcs11/Signature/TestDSA.java
    sun/security/pkcs11/Signature/TestRSAKeyLength.java
    sun/security/pkcs11/Signature/TestDSAKeyLength.java
    sun/security/pkcs11/Signature/ByteBuffers.java
    sun/security/pkcs11/rsa/TestSignatures.java
    sun/security/pkcs11/rsa/TestCACerts.java
    sun/security/pkcs11/ec/TestCurves.java
    sun/security/pkcs11/ec/TestECDSA.java
    sun/security/pkcs11/Signature/TestDSAKeyLength.java


The failures are caused by a CKR_OPERATION_ACTIVE error in PKCS11.
For example,

java.security.ProviderException: Initialization failed

The root cause is a Solaris bug already fixed in Solaris 11.2
