Description James Livingston 2013-08-28 05:46:34 UTC

Due to https://issues.jboss.org/browse/JBTM-1431, it is possible for a last resource (e.g. non-XA resource) to be committed prior to another XA resource, which is unsafe.

This was fixed in master prior to 6.1, but not in a bugfix release so was not pulled into EAP.

Comment 1 James Livingston 2013-08-28 22:36:19 UTC

Fix backported to 4.17 branch by Tom, https://github.com/jbosstm/narayana/commit/986d7792d2dbcc5d01844a5f2240a31a1f5d78b2

Comment 2 JBoss JIRA Server 2013-10-14 11:55:47 UTC

Tom Jenkinson <tom.jenkinson> updated the status of jira JBTM-1431 to Closed

Comment 5 tom.jenkinson 2014-12-05 12:42:36 UTC

Went into 4.17.9

Comment 6 Hayk Hovsepyan 2014-12-08 14:29:46 UTC

Verified on revision EAP 6.4.0.DR12.
Last resource is committed before XA resources.

For safety reasons the "Commit Markable Resource" is added in EAP 6.3.0. (http://documentation-devel.engineering.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/6.3/html-single/Development_Guide/index.html#sect-About_the_LRCO_Optimization_for_Single-phase_Commit_1PC)
