Cannot checkout node

[predatorro666]

Hi everyone,

After migration from Modeshape 4 to 5, we found the next strange behavior in versioning:

Saying we have the next structure:

[kn:node] > kn:base, mix:etag, mix:lockable, mix:referenceable, nt:unstructured
[kn:versionableNode] > kn:node, mix:versionable
[kn:folder] > kn:base, mix:etag, mix:lockable, mix:referenceable, nt:unstructured, mix:versionable

[kn:category] > kn:versionableNode

 - kn:id (STRING)
 + kn:caAttributes (kn:caAttributes)
...

[kn:categoriesFolder] > kn:folder
 + kn:categoryItem (kn:category) SNS

[kn:kbase] > kn:versionableNode
 - kn:id (STRING)
 + kn:categories (kn:categoriesFolder)
...

Saying we have the next node with path

/03ebay_101/kn:categories/31b11ea9-5f40-48a4-a582-dd04285b0fe1_en

After accessing/writing to the root node (kn:kbase) it is impossible to change child node (kn:category) because of exception:

'/03ebay_101/kn:categories/31b11ea9-5f40-48a4-a582-dd04285b0fe1_en' (or its nearest versionable ancestor) is checked in, preventing this action

Trying to checkout this node has no effect

session.getWorkspace().getVersionManager().checkout(itemNode.getPath())

but

session.getWorkspace().getVersionManager().isCheckedOut(itemNode.getPath())

give us 'false'

All the root nodes, which I suppose, must be the only ancestors for the current node, are checkedOut. We can see it when request parents one by one:

session.getWorkspace().getVersionManager().isCheckedOut(itemNode.getParent().getParent().getParent().getPath())              //root node - '/'

session.getWorkspace().getVersionManager().isCheckedOut(itemNode.getParent().getParent().getPath())                                 //kn:kbase node - '/03ebay_101/'

session.getWorkspace().getVersionManager().isCheckedOut(itemNode.getParent().getPath())                                                    ///kn:categoriesFolder' - '03ebay_101/kn:categories/'

All operations are made under one session which is connected to the web-request. Turning off transactions have no effect.

After some tracing I see that check out is happened here

org.modeshape.jcr.JcrVersionManager#checkout(org.modeshape.jcr.AbstractJcrNode)

versionable.setProperty(versionSession, props.create(JcrLexicon.IS_CHECKED_OUT, Boolean.TRUE));

IsCheckedOut method is here
org.modeshape.jcr.AbstractJcrNode#isCheckedOut

And here we have different session cache where related node has property IsCheckedOut = false
