In case of transaction error ( writeBlocking ) realm doesn't cancel the transaction which lead to "The Realm is already in a write transaction" exception

[abdou-gh549]

How frequently does the bug occur?

Always

Description

When i use writeBlocking for a write transaction and i get
"java.lang.IllegalArgumentException: Cannot import an outdated object. Use findLatest(object) to find an up-to-date version of the object in the given context before importing it ".
realm doesn't cancel the transaction which lead to the next one to fail because of RLM_ERR_WRONG_TRANSACTION_STATE ( realm already in write transaction )

to handle it in my case i had to add another try catch in my transaction to cancel it in case of unexpected error

when i looked into writeBlocking i found out that the only case when realm cancel the transaction is IllegalStateException

as a library user i think that opening / closing a transaction is realm responsibility, correct me if i am wrong
