Software developers working on multi-language systems with various debug tools (BPEL, AE, Java, etc.) can use a common debug adaptor (CDA). The CDA implements a method of debugging in a multi-computer program language environment. The method includes registering various debug tools associated with different programming languages in the multi-computer program language environment, each one of the plurality of debug tools providing suspended threads and stack frames in response to a debug event in the multi-computer program language environment. The method can further include receiving the suspended threads and stack frames from the plurality of debug tools. The method can further include correlating the received suspended threads and stack frames under a common suspended thread; and providing the common suspended thread in a debug view. Such a method can have a number of attributes intended to assist developers facing debugging problems in multi-language systems.
