{noformat}Java.lang.NullPointerException: Cannot invoke
"org.hibernate.sql.ast.tree.expression.CaseSearchedExpression$WhenFragment.getPredicate()"
because "whenFragment" is null
at
org.hibernate.sql.ast.spi.AbstractSqlAstTranslator.visitAnsiCaseSearchedExpression(AbstractSqlAstTranslator.java:6431){noformat}
We recently updated to 6.2.4 from 5.x and started occasionally seeing large spikes of
errors with this stacktrace. One pod, out of dozens, will suddenly start getting this
error for about 10% of findById queries on a specific Repository and continue until it is
manually killed. We’ve been unable to figure out how to reproduce the issue, but it seems
to correlate with high system load.
{noformat} @Query("SELECT p FROM TblEntity e WHERE e.id = :id")
Optional<TblEntity> findById(@Param("id") long id);{noformat}
This the line in the code where the NPE occurs
{noformat} for ( CaseSearchedExpression.WhenFragment whenFragment :
caseSearchedExpression.getWhenFragments() ) {
...
whenFragment.getPredicate().accept( this ); // <-- NPE, whenFragment is null somehow
...
}{noformat}
