org.hibernate.property.BasicPropertyAccessor.getterMethod(Class, String) tries to find the getter for a given bean property.

This might fail, if there are a getter and an 'isser' for that property:

public class Entity {
    @ManyToOne
    SomeType getValue() {}

    @Transient
    boolean isValue() {}
}

Such code might exists for convenience, e.g. to check if a property is not null or initialized or whatever.

The outcome of org.hibernate.property.BasicPropertyAccessor.getterMethod(Class, String) depends on the order of the result of Class.getDeclaredMethods, which depends on the current environment, heavily.

Attached you'll find a Testcase that tries to reproduce that behavior. Unfortunately it's impossible to reproduce this issue on all executions of this test case, because of the randomndess nature of this issue.
