Browse Source 
2005-03-17  Andrew Haley  <aph@redhat.com>

	* java/lang/natVMSecurityManager.cc (getClassContext): Add new
	arg: klass.
	Pass klass to _Jv_StackTrace::GetClassContext().
	* java/lang/ClassLoader.java (getParent): Pass class to
	VMSecurityManager.getClassContext()
	(getSystemClassLoader): Likewise.
	* java/lang/Package.java (getPackage): Likewise.
	(getPackages): Likewise.
	* java/lang/SecurityManager.java (getClassContext): Likewise.
	(currentClassLoader): Likewise.
	* java/lang/VMSecurityManager.java: (getClassContext): Likewise.
	(currentClassLoader) Add new arg: caller.
	Pass caller to VMSecurityManager.getClassContext.

	* stacktrace.cc (GetClassContext): Correct calculation of
	jframe_count.

	* boehm.cc (_Jv_MarkObj): (_Jv_MarkObj): Mark
	im->source_file_name.
