  • Version of JMockit that was used:
    1.41 and 1.43
    maven 3.3.9 or 3.2.5
    Java 1.8.0_181

  • Description of the problem:
    A test adds an expectation which involves a class called Person.class
    This has a property like this
    @RestApiField(metaDataName = FieldDefinitionConsts.FIELD_DEFINITION_CAN_BE_USER, getterMethod = "isCanBeUser", fieldType = boolean.class)
    private String canBeUser = StringUtil.FALSE;
    The property fieldtype is defined as
    Class<?> fieldType() default Null.class;

This results in an IllegalArgumentException
java.lang.IllegalArgumentException: Invalid type descriptor: Z
if the test is executed via maven (see stack below)
strangely in my Ecplise IDE it works.

If I change the fieldType property to Boolean.class it works.
In case of the primitive class type boolean.class the internal "strings" array contains this Z (which indicated a primitive boolean):
... canBeUser, CanBeUser, getterMethod, isCanBeUser, fieldType, Z, canbeuser, ....

Should the method
mockit.asm.ReferenceType.getReferenceType(char[], int)
Also support the primitive Class types

I quickly created a testcase which reflects our environment.
Within the latest jmockit checkout execution fails (also in my IDE now :-) )
Thx for support
