The test java/lang/Class/getDeclaredField/FieldSetAccessibleTest.java verifies that all fields returned by getDeclaredFields() can be set accessible (see JDK-8065552). The test attempts to verify all classes from all jar files that can be found in the boot classpath. It works fine on JRE but fails on compacts.

Here's one of possible failures observed on Compact Profile 1:

java.lang.NoClassDefFoundError: Ljavax/security/auth/kerberos/KerberosPrincipal;
        at java.lang.Class.getDeclaredFields0(Native Method)
        at java.lang.Class.privateGetDeclaredFields(Unknown Source)

java.lang.RuntimeException: Test failed for the following classes: [sun/security/ssl/krb5/KerberosClientKeyExchangeImpl$1.class, sun/security/ssl/krb5/KerberosClientKeyExchangeImpl.class]

This happens because the sun.security.ssl.krb5.KerberosClientKeyExchangeImpl class have a field of type javax.security.auth.kerberos.KerberosPrincipal whereas Compact 1 doesn't include javax.security.auth.kerberos package. Thus the dependency on KerberosPrincipal cannot be satisfied and NoClassDefFoundError exception is raised.

The class sun.security.ssl.krb5.KerberosClientKeyExchangeImpl is found in jsse.jar. When this jar is simply removed from the boot classpath all tests pass OK.
