Spring Avoid virtual thread pinning in procedure calling

Virtual thread pinning in procedure calling

Hi, I am using Java 21, spring boot 3.3.2

When I enablevirtual threads and -Djdk.tracePinnedThreads=short I got virtual thread pinning and deadlock my requests.

The pinning log :

Thread[#179,ForkJoinPool-1-worker-28,5,CarrierThreads] org.springframework.jdbc.core.simple.AbstractJdbcCall.compile(AbstractJdbcCall.java:298) <== monitors:1

I review the code there used synchronized in method level. Could we change it to java locking library.

public final synchronized void compile() throws InvalidDataAccessApiUsageException {
        if (!isCompiled()) {
            if (getProcedureName() == null) {
                throw new InvalidDataAccessApiUsageException("Procedure or Function name is required");
            }
            try {
                this.jdbcTemplate.afterPropertiesSet();
            }
            catch (IllegalArgumentException ex) {
                throw new InvalidDataAccessApiUsageException(ex.getMessage());
            }
            compileInternal();
            this.compiled = true;
            if (logger.isDebugEnabled()) {
                logger.debug("SqlCall for " + (isFunction() ? "function" : "procedure") +
                        " [" + getProcedureName() + "] compiled");
            }
        }
    }

@jhoeller Can I optimize this problem? I will use CAS lock free processing for this scenario.
