Hi Matthias, looks good to me.
Maybe you want to create a Macro for the repeating pattern: graphicsConfigs[ind] = ZALLOC (_AwtGraphicsConfigData); if (graphicsConfigs[ind] == NULL) { JNU_ThrowOutOfMemoryError(env, "allocation in getAllConfigs failed"); goto cleanup; } in getAllConfigs?

It deals with return value checking of ZALLOC . ZALLOC is a macro using calloc, please see : jdk/src/java.desktop/unix/native/common/awt/awt_p.h /* allocated and initialize a structure */ #define ZALLOC(T) ((struct T *)calloc(1, sizeof(struct T))) ... so the return value has to be checked which is missing at some places.
