OJVM in PDB Fails With ORA-29532:BootstrapMethodError, ORA-07445:[joevm_invokevirtual] or Other Errors When Moving to Newer Release or Patch Level (Doc ID 2488247.1)

The purpose of this note is to aid in identifying pluggable databases (PDB)s where the data dictionary has been corrupted by bug 28745878 and providing a solution for repairing such PDBs.  The subject of the note includes some common symptoms of this situation but it should be recognized that there can be other symptoms and that any of these symptoms may have other causes.  When present in a multitenant database (CDB), bug 28745878 can cause corruption of the system dictionary in a PDB when the PDB is created.  Even if the bug itself is subsequently fixed in the CDB, affected PDBs will remain corrupted until the solution given in this note is applied.  The corruption will typically be asymptomatic at first.  Only when the CDB containing the PDB has been upgraded to a new release level or patched to a new PSU or RU level in which java system classes have changed are symptoms liable to be observed.  The symptoms therefore often manifest for the first time during the upgrade or patch post installation actions.  The corruption only occurs in PDBs that are created by plugging a non-CDB into a CDB in which bug 28745878 is present.  Additionally, the corruption occurs only if long identifiers are in use in the CDB  but were not yet in use in the non-CDB.  When any of the symptoms described here occur in any other context, particularly in the root container, they are due to some cause other than bug 28745878.  The solution given in this note should not be attempted in such cases.  In particular the solution can cause irreversible damage if attempted in the root container.
