      "message": "Fix transaction aborting\n\nDuring compilation, a java.lang.InternalError is used to indicate\nthat class initialization failed and the enclosing transaction\nshould be aborted and the changes rolled back. However there is\nnothing preventing the code executed from a class initializer from\ncatching that exception (like catching Throwable and ignore it).\nTherefore we may return from the class initializer with no pending\nexception, even if the transaction was aborted, and not rollback\nthe changes properly.\n\nTo fix this, we now rely on the new Transaction::aborted_ field to\nknow whether a transaction aborted. When returning from the class\ninitializer without pending exception, we now check wether we aborted\nthe enclosing transaction. If that\u0027s the case, we set the status of\nthe class to kStatusError and throw a new java.lang.InternalError\nwith the original abort message.\n\nThis CL also contains some cleanup:\n- Renames Transaction::Abort to Transaction::Rollback which is less\nambiguous and more reflect what is done.\n- Moves the code throwing the java.lang.InternalError exception into\nthe Transaction::ThrowInternalError method so we do not duplicate\ncode. Now we may abort transaction more than once (because we may\nhave caught the java.lang.InternalError then execute code causing\nnew transaction abort), we only keep the first abort message to\nthrow the exception.\n- Updates transaction_test with more cases and more checks.\n- Bumps oat version to force recompilation with this fix.\n\nBug: 19202032\nChange-Id: Iedc6969528a68bbdf3123146e990df4dbc57834b\n"

This only\nconcerns class initialization happening at compilation time when generating an\nimage (like boot.art for the system).\n\nIn transactional mode, we log every object\u0027s field assignment and array update.\nTherefore we\u0027re able to abort a transaction to restore values of fields and\narray as they were before the transaction starts. We also log changes to the\nintern string table so we can restore its state prior to transaction start.\n\nSince transactional mode only happens at compilation time, we don\u0027t need to log\nall these changes at runtime. In order to reduce the overhead of testing if\ntransactional mode is on/off, we templatize interfaces of mirror::Object and\nmirror::Array, respectively responsible for setting a field and setting an\narray element.\n\nFor various reasons, we skip some specific fields from transaction:\n- Object\u0027s class and array\u0027s length must remain unchanged so garbage collector\ncan compute object\u0027s size.\n- Immutable fields only set during class loading: list of fields, method,\ndex caches, vtables, ... as all classes have been loaded and verified before a\ntransaction occurs.\n- Object\u0027s monitor for performance reason.\n\nBefore generating the image, we browse the heap to collect objects that need to\nbe written into it. Since the heap may still holds references to unreachable\nobjects due to aborted transactions, we trigger one collection at the end of\nthe class preinitialization phase.\n\nSince the transaction is held by the runtime and all compilation threads share\nthe same runtime, we need to ensure only one compilation thread has exclusive\naccess to the runtime. To workaround this issue, we force class initialization\nphase to run with only one thread. Note this is only done when generating image\nso application compilation is not impacted.
